Founding edition — these numbers are real, small, and growing. When the agent door opens, this board goes live.
Three shelves are not on display at the founder’s request — Shelf #8 · PEG feeding and survival, Shelf #11 · BMI and ICU extubation and Shelf #22 · Elevated phosphate on admission as a danger signal. Their cards are kept on file, and the counts above cover only the shelves shown.
Latest deposit · Oct 23, 2026 · Deposit #21 — full-text recovery: 5 cards added across Shelves #4, #11, #14 and #15 · All passed the source check against the full papers.
The question: Does giving albumin change survival — and what do the level, and its fall, tell you?
The balance of the evidence: Giving albumin as a fluid does not change overall survival (SAFE; ALBIOS), with a hypothesis-generating hint in severe sepsis. The level and its trajectory are strong prognostic signals — persistently low or falling is worse, rising is better — but nearly all trajectory evidence is retrospective, and this shelf grades it Low, honestly. The resuscitation trials match the measurement lesson: albumin as a drug shows no overall mortality advantage; albumin as a measurement predicts by its trajectory, not its door value.
The question: Where does albuminuria risk actually begin — and what drives progression?
The balance of the evidence: Risk begins well inside the “normal” range — progression risk roughly doubles above a urine albumin of ~8.4 mg/g in type 2 diabetes, far below the standard 30 mg/g boundary, which is a consensus classification line rather than a risk inflection. Over decades, blood pressure drives albuminuria up, while blood pressure, smoking, and cholesterol drive kidney function down — and falling kidney function mechanically raises measured albuminuria on its own.
The question: Does vitamin D prevent or soften infections in adults — respiratory, tuberculosis, COVID-19, critical illness?
The balance of the evidence: The newest and largest synthesis (Jolliffe 2025) finds vitamin D’s overall effect on acute respiratory infection borderline and not significant (OR 0.94, p=0.057), with a residual signal in daily dosing (0.84) — while the dramatic 2017 benefit in the severely deficient (aOR 0.30) did not survive as effect modification in the update. Tuberculosis prevention shows no benefit; a critical-illness mortality signal (RR 0.78) rests on small trials and a route subgroup. Correcting deficiency remains sensible care; vitamin D is not a proven shield against infection in adults. The children evidence now lives on its own shelf, #37.
Shelf note: Cards 7 and 13 both concern the single D-Health trial — do not count them as independent evidence.
Ginde AA, Blatchford P, Breese K, et al. High-dose monthly vitamin D for prevention of acute respiratory infection in older long-term care residents: a randomized clinical trial. J Am Geriatr Soc. 2017;65(3):496–503. PMID 27861708. 107 long-term-care residents aged ≥60 were randomized to monthly vitamin D3 100,000 IU or standard-dose care for 12 months. Acute respiratory infections fell: 0.67 vs 1.11 per person-year (IRR 0.60, 95% CI 0.38–0.94). But falls more than doubled: 1.47 vs 0.63 per person-year (IRR 2.33, 95% CI 1.49–3.63), with fractures unchanged (0.10 vs 0.19 per person-year, NS). Achieved 25-hydroxyvitamin D was 32.6 vs 25.1 ng/mL; no hypercalcemia or kidney stones occurred. A benefit and a harm in the same small trial — high-dose D in the frail elderly is a trade, not a free win.
The question: What does low phosphate do to breathing muscles, ventilator weaning, and survival?
The balance of the evidence: Low phosphate travels with weak breathing muscles and harder ventilator weaning — the 1988 classic showed strength returning as phosphate was repleted, but nothing here is randomized, and the weaning data rest on handfuls of events.
Editor’s note · Oct 23, 2026 — the founding editor reframed this shelf’s question to center low phosphate; the high-phosphate data are limited and stay labeled as such.
Editor’s note · Oct 24, 2026 — Split at the founding editor’s direction: this shelf now holds only the low-phosphate thread; the admission-signal cards moved to Shelf #22. A refeeding/replacement thread is held until the sixteen unverified leads are checked.
The question: How big is the treatment gap, how many people have diabetes — and what happens when medicines are dispensed in longer supplies?
The balance of the evidence: The gap is measured: statin use after heart disease or stroke is 14.6% worldwide, and no low- or middle-income region reaches the WHO 50% target. The population is counted: 589 million adults with diabetes, 42.8% undiagnosed. Longer supplies travel with better continuation wherever observed — 90 vs 30 days after heart procedures, and a full year of contraception. What does not exist anywhere on this shelf is a randomized trial of a full year’s supply of chronic medicines — that empty space is the trial this project exists to run.
The question: Does a lower serum albumin go with more coronary calcium and faster progression — and does LDL matter only when coronary calcium is present?
MeSH: Serum Albumin · Coronary Artery Disease · Vascular Calcification · Atherosclerosis · Hypercholesterolemia · Disease Progression · Risk Factors · Longitudinal Studies
ICD-10: E88.09 Hypoalbuminemia · I25.1 Coronary atherosclerosis · ICD-11: BA52 Coronary atherosclerosis
LOINC: 1751-7 Albumin · 1975-2 Bilirubin, total
The balance of the evidence: Within the normal range, lower albumin goes with more coronary calcium and faster progression (Korea, Taiwan) — but the link is fragile: in the Taiwan cohort the coronary-calcium association disappeared once age was accounted for, and nothing on this shelf is randomized. The shelf’s strongest card is about LDL, not albumin: in 23,132 Danish patients, LDL predicted heart attacks and strokes only when coronary calcium was already present. Albumin here behaves as a marker travelling with age and inflammation — not a proven lever.
Supplement · Oct 23, 2026 — a recovery pass (Deposit #20) added the CLARIFY card below and identified the original deposit’s unidentifiable ‘Dong et al.’ citation as this paper.
Shelf note: Two further cards in this deposit — the SAFE trial and the ALBIOS trial — already live on Shelf #2 and are not counted twice.
The question: What does a squeeze of the hand predict — about dying, and about coming off a ventilator?
The balance of the evidence: In the community, weaker grip is one of the most consistent mortality signals in epidemiology — per 5 kg lower grip, death rates run about 16–20% higher in half a million UK Biobank participants, dose-responsive across 3.1 million people pooled — and an uneven grip between the hands adds a further ~12%. In the ICU the picture splits: grip tracks difficult and prolonged weaning, but the largest study found it did not predict extubation failure, and the pooled extubation difference was not significant. Grip is a strong risk marker; nothing on this shelf shows that strengthening it changes outcomes.
Shelf note: Card 16 carries a Tier 3 badge: its two odds ratios match the published abstract, but the sample size and grip cutoff could not be checked.
The question: Does zinc — in the blood, by mouth, or on the skin — change whether diabetic foot and leg ulcers heal?
The balance of the evidence: Low zinc is common where ulcers are — 26.9% deficient in a prospective foot-clinic cohort — and lower zinc travels with ulcer presence and slower early healing. But the one prospective healing cohort found baseline zinc did not predict who healed (HR 1.05), and giving zinc is unproven: the positive diabetic-ulcer trial carries a 2024 Expression of Concern, the combined-nutrient pilot was neutral at 12 weeks, and Cochrane’s pooled verdict for venous ulcers is no benefit. Topical zinc has older, small positive trials. On this shelf, association does most of the work.
Shelf note: Card 8’s trial is the subject of a 2024 Expression of Concern — printed on the card itself.
The question: What is cancer cachexia, how much does it shorten life, and can anything be done about it?
The balance of the evidence: The definition is settled (Fearon 2011: weight loss >5%, or >2% with BMI <20 or sarcopenia — three stages) and the prognosis is precisely grim: median survival falls stepwise from 20.9 months (grade 0) to 4.3 months (grade 4) in 8,160 patients, CT muscle measures predict survival far better than BMI alone (concordance 0.92 vs 0.73), and sarcopenic obesity carries a fourfold mortality hazard. The mechanisms are real biology — lipolysis switched on, tumor PTHrP browning fat, MIC-1 switching appetite off, tumor vesicles driving muscle wasting through TLR4, glucose recycling running fivefold through the Cori cycle while glycogen stores empty, and autophagy switched on in muscle with its cleanup stalled — but treatment remains the honest gap: anamorelin adds lean mass in two phase III trials yet did not improve grip strength, a multimodal program preserved weight only in a small feasibility trial, and nothing on the shelf reverses the syndrome.
The question: What actually works to keep patients on their statins?
MeSH: Medication Adherence · Hydroxymethylglutaryl-CoA Reductase Inhibitors · Acute Coronary Syndrome · Secondary Prevention · Reminder Systems · Humans
ICD-10: I25.1 Atherosclerotic heart disease · E11.9 Type 2 diabetes mellitus without complications · ICD-11: BA52 Coronary atherosclerosis · 5A11 Type 2 diabetes mellitus
Intensity works, nudges barely do: pharmacist-led multifaceted care after a heart event lifted statin adherence to 93.2% vs 71.3%, while automated reminders bought only 2–3 points, decision support was borderline (OR 1.18), texts did nothing (RR 0.93), a reminder device and a risk mailer were both null — and pharmacist counseling’s early persistence benefit was gone by 12 months.
Editor’s note · Oct 23, 2026 — split from the combined shelf at the founding editor’s direction: statin compliance here, A1C compliance on Shelf #20. The 9 recommendation-burden cards now appear on Shelf #135 and Shelf #20 by design — they are evidence of compliance with whatever medication — and are counted once in the library total.
Editor’s note · Oct 23, 2026 — Shelf #1 (statin continuation) merged into this shelf at the founding editor’s direction: compliance and continuation are one shelf; A1C compliance remains separate on Shelf #20.
Re-verification · Oct 23, 2026: the three cards formerly marked Tier 3 (TEXTMEDS, EMPOWER-D, Reuben 1996) were re-checked against their full primary papers in Deposit #19 and are now Tier 1 · Source-verified. All cards on this shelf are now Tier 1.
The question: In sepsis and septic shock, do cortisol levels, the ACTH stimulation response, and cortisol’s binding protein predict who dies — and does treating a blunted response help?
The balance of the evidence: The ACTH test sorts septic-shock patients by risk (26/67/82%), and the shelf now anchors how common failure is — 9% of severe-sepsis patients fail the test, split between secondary adrenal insufficiency and adrenal dysfunction — and the mechanism underneath: cortisol alone raises glucose production entirely through gluconeogenesis, and growth hormone raises it by sustaining glycogenolysis. The treatment evidence is still one 43-patient pilot.
Supplement · Oct 23, 2026 — Deposit #21 (full-text recovery) added the card below.
Eight cards on this shelf are Tier 3 · Abstract-checked — their numbers are verified in the primary publication’s abstract; full-text checking is still pending.
Editor’s note · Oct 24, 2026 — Three of the founder’s own papers join the shelf (Manglik 2003, Khani 2001, Ghanaat 2005), shelved on their merits like his 1995 and 2022 papers already here; the Ghanaat card is fasting physiology, not sepsis — it sits here because the shelf follows the stress hormones.
The question: Does feeding hospitalized patients — on the wards and around surgery — help them live longer?
The balance of the evidence: On the medical wards and around surgery, feeding works: individualized nutritional support cut 30-day mortality in EFFORT (7% vs 10%, aOR 0.65), a specialized supplement halved 90-day mortality in NOURISH (RR 0.49, a secondary endpoint), and perioperative nutrition cut hospital deaths in malnourished GI-cancer patients (Wu 2006, 2.1% vs 6.0%). The founding caution stands: the thin and recent-weight-loss subgroups are almost never reported separately.
✓ LEVEL A — Founder-approved under the Level A rule, Oct 25, 2026.
Editor’s note · Oct 23, 2026 — this shelf was split at the founding editor’s direction: hospitalized, yes; ICU, no (see Shelf #21). The ICU trials that were here moved, unchanged, to Shelf #21.
Supplement · Oct 23, 2026 — Deposit #21 (full-text recovery) added the card below.
One card on this shelf is Tier 3 · Abstract-checked — its numbers are verified in the primary publication’s abstract or publisher record; full-text checking is still pending.
The question: Do immune-modulating feeds and nutrients — arginine, fish oil, RNA, antioxidants, vitamin A — change outcomes in critically ill and septic patients?
The balance of the evidence: Thirty years of immunonutrition in one shelf, and it argues with itself: the early surgical and trauma trials were positive (Kudsk — pneumonia 11.8% vs 31% with enteral feeding; Daly — complications 11% vs 37%), and Galbán’s septic-patient trial cut mortality — yet the one severe-sepsis immunonutrition trial was stopped for harm (ICU mortality 44.4% vs 14.3%), and the nitric-oxide lesson looms over the whole arginine idea (blocking NO in septic shock raised mortality, 59% vs 49%). Fish oil pools positive (RR 0.74) but leans on small heterogeneous trials, the founder’s own vitamin A trial was negative, and two physiology cards explain why the field keeps trying: muscle ATP collapses within a week of critical illness, and septic hypoalbuminemia is a distribution problem, not a synthesis problem.
Editor’s note · Oct 24, 2026 — Restored the same day it was paused, after the founder lifted the pause: every card here is published material with its source attached; the unpublished AIM Trial manuscript was never carded.
Six cards on this shelf are Tier 3 · Abstract-checked — their numbers are verified in the primary publication’s abstract; full-text checking is still pending.
The question: Does pre-existing diabetes change a critically ill patient’s chance of dying?
The balance of the evidence: The shelf now says something sharper: pre-existing diabetes does not raise sepsis mortality — in 16,497 Taiwanese ICU patients it was identical (22.6% vs 22.6%), and across nine studies known diabetics died at half the rate of patients with new-onset hyperglycemia (12.5% vs 26.7% in hospital) at similar glucose levels, as if prior exposure adapts the body to hyperglycemia. The metabolic parallel is real — diabetes shares cancer’s raised glucose production and leucine turnover — but the albumin card (54% higher death rate per 0.5 g/dL lower) is a different population, transplant-listed lung disease, and the shelf’s mechanism section (glucose variability) still awaits its papers.
Editor’s note · Oct 24, 2026 — The founder’s own 2012 paper (with his son Chandler, first author) joins as card 2, alongside Richardson 2002 and Zisman 2009. The shelf’s hold is lifted with this build; the glucose-variability mechanism section still awaits Monday’s papers.
The question: For the supplements patients actually take, what does the randomized evidence show about benefit?
The balance of the evidence: The shelf sorts into three piles: real but mostly modest benefits — potassium salt substitute cut stroke and death in a 21,000-person trial, vitamin E improved liver histology without improving fibrosis, and psyllium, creatine with training, melatonin, ginger, curcumin, and cranberry each show small, specific, replicated effects on surrogate or symptom endpoints — plus one lonely hard-outcome positive, CoQ10 in heart failure (HR 0.50), unreplicated since 2014. And a harm pile every supplement conversation needs: vitamin E raised prostate cancer in SELECT (HR 1.17), an annual mega-dose of vitamin D increased falls and fractures, and beta-carotene with vitamin A raised lung cancer in smokers (CARET, stopped early) — the pattern being that replacement-level uses behave, while pharmacologic mega-doses in healthy people are where the harm lives.
Editor’s note · Oct 24, 2026 — Restored the same day it was paused, after the founder lifted the pause: every card here is published material with its source attached; the unpublished supplements guides and the in-press paper’s own analyses were never carded. Question is benefit-only by the founder’s reframe; the three harm cards stay labeled as context, not a harm review.
Two cards on this shelf are Tier 3 · Abstract-checked — their numbers are verified in the primary publication’s abstract; full-text checking is still pending.
The question: Is a LOW admission creatinine a danger signal for death — not just a high one?
The balance of the evidence: Low creatinine as a frailty signal gains its mechanism: in 118 hemodialysis patients the creatinine-based estimate of lean body mass matched DEXA with a mean difference of zero — but the authors present it as a hypothesis, and the shelf still has no study that measured muscle mass directly against mortality.
Editor’s note · Oct 24, 2026 — The founder’s own 2013 paper (Patel, with Tayek third author) joins as card 3: creatinine as a muscle-mass marker, presented as a hypothesis with a pilot behind it. The desk caught that the abstract prints no correlation coefficient — none is printed on the card.
The question: What actually moves A1c — and how many recommendations can a patient carry?
Remote diabetes care works when it adjusts medicines: DiaTel −1.7 vs −0.8 points, comprehensive telehealth −0.61 against monitoring alone, pharmacist-coach mobile health −0.62, Thai tele-insulin titration −0.65 — but gains fade (EMPOWER-D’s advantage gone by 12 months) and teleconsultation is non-inferior to in-person care. Underneath all of it, the same burden literature: one ‘most important’ label doubled implementation, five or more recommendations cut action, and delayed recall collapses at 3–4 instructions — with one large dissent (Press) arguing the bottleneck is the patient’s memory, not the physician’s list.
Editor’s note · Oct 23, 2026 — split from the combined shelf at the founding editor’s direction: A1C compliance here, statin compliance on Shelf #13. The 9 recommendation-burden cards appear on both shelves by design — they are evidence of compliance with whatever medication — and are counted once in the library total.
The question: In the ICU, does feeding more — more energy, more protein, earlier — help patients live longer?
The balance of the evidence: In the ICU, every large trial of more is neutral: energy-dense formula (RR 1.05), higher protein (RR 1.08), augmented protein (RR 0.99 alive), full vs trophic feeding, permissive underfeeding (RR 0.94) and early restriction in shock all cross no-difference. Whether thin patients are the exception is untested — none of these trials isolated them.
✓ LEVEL A — Founder-approved under the Level A rule, Oct 25, 2026.
Editor’s note · Oct 23, 2026 — born by split from Shelf #15 at the founding editor’s direction.
Five cards on this shelf are Tier 3 · Abstract-checked — their numbers are verified in the primary publication’s abstract or publisher record; full-text checking is still pending.
The question: In adults with hypertension, does chlorthalidone (long half-life, roughly 60 hours) give better cardiovascular, stroke, or mortality outcomes than hydrochlorothiazide (short half-life, roughly 6 hours) — and at what cost in potassium, sodium, and kidney effects?
The balance of the evidence: The head-to-head trial found no cardiovascular advantage for chlorthalidone over hydrochlorothiazide (HR 1.04, null) — but chlorthalidone lowers ambulatory and nighttime pressure more in small comparisons, and costs more potassium wherever it is measured head-to-head or matched (HR 1.38 in the trial, 1.70 in Ontario, 2.72 in LEGEND). The longer half-life buys pressure control, not proven outcome benefit — which is exactly what the founder’s individual-data paper is designed to test.
Editor’s note · Oct 24, 2026 — Deposit #22. The founder’s individual-patient-data paper on this question is in progress and unpublished; it is withheld by title only and contributes no numbers here. ALLHAT subgroup and follow-up publications are one parent trial, DCP secondary reports are one parent trial, and PEAR/PEAR-2 may overlap — none is double-counted. One card (Finnerty 1976) runs counter to the larger potassium pattern on small historical subgroup counts; do not over-read it.
The question: In US health centers, why do diabetes control rates differ by race and ethnicity — and what closes the gap?
The balance of the evidence: Black patients run a few points worse than White patients in every UDS era, and the gap survives access and adherence adjustment — it is not only a clinic-door problem. Asian patients run lowest on poor control even though they are tested least, which strengthens rather than weakens the finding — but ‘Asian’ aggregates subgroups that differ, and lumping Asian with NHPI hides the NHPI gap, where published control numbers barely exist.
Editor’s note · Oct 24, 2026 — All 27 cards are abstract-checked (Tier 3); no card here rests on a full-text check. Two abstracts were cut off before their main results (Wallia 2024, Xiao 2026) and are flagged on their cards. The founder’s own LA County analysis (2025 UDS, 59 centers) is unpublished and contributes no numbers here; it joins as a card when published or presented. Open questions, not cards: (1) the access hypothesis — that the four worst groups in LA County’s 2025 data (NHPI, multiracial, AI/AN, Black) have less access and consistently higher A1cs, likely with higher cardiovascular outcomes, and how access for those groups improves; (2) the Asian advantage — what explains the low Asian poor-control rate despite lower testing; subgroup disaggregation, phenotype, diet, family support, language-concordant services, and immigrant effects are candidates to test, not findings; (3) cardiovascular outcomes by group are not measured in UDS data.
The question: Does potassium — as tablets, or as potassium-enriched salt — lower blood pressure, and does it prevent strokes, heart attacks, and death?
The balance of the evidence: Potassium lowers pressure modestly — about 4–5 mmHg systolic in meta-analyses, near 7 in untreated hypertension — but the one trial in high-normal pressure faded by 6 months, and the only hard-outcome win combined sodium cutting with potassium enrichment, so it doesn’t prove potassium tablets prevent strokes. The mechanism is plausible; the tablet benefit is pressure, not proven outcomes.
Editor’s note · Oct 24, 2026 — Restored the same day it was paused, after the founder lifted the pause: every card here is published material with its source attached. Keep oral potassium blood-pressure evidence separate from salt-substitute cardiovascular-outcome evidence. The four mechanism cards (Aburto, Gu, Whelton, Yin) overlap — the meta-analyses share trials, and Yin 2022’s outcome figures are driven mainly by SSaSS (already on this shelf). Read them as one corroborated mechanism, not four separate wins.

Twenty-two randomised trials (1,606 participants): higher potassium intake lowered systolic BP by 3.49 mmHg (95% CI 1.82–5.15) and diastolic by 1.96 (0.86–3.06) — an effect seen in people with hypertension but not without; at intakes of 90–120 mmol/day the systolic fall was 7.16 mmHg. In 11 cohort studies (127,038 participants), higher intake was associated with stroke RR 0.76 (0.66–0.89); the cardiovascular-disease and coronary associations were not significant. No significant adverse effect on renal function, lipids, or catecholamines. Caution: the stroke figure is observational — the trials prove pressure, the cohorts suggest stroke.
Gu D, He J, Wu X, Duan X, Whelton PK. Effect of potassium supplementation on blood pressure in Chinese: a randomized, placebo-controlled trial. J Hypertens. 2001;19:1325–1331. PMID 11446724. In a high-sodium, low-potassium Beijing community sample, 150 adults aged 35–64 with systolic 130–159 and/or diastolic 80–94 mmHg received 60 mmol/day potassium chloride or placebo for 12 weeks. Systolic BP fell 5.00 mmHg (95% CI −7.88 to −2.13, P<0.001); diastolic fell 0.63 (not significant). Urinary potassium excretion rose 20.6 mmol/24 h. One 12-week trial in one city, and diastolic did not move — but this is the closest single trial to a six-point systolic fall.
Whelton PK, He J, Cutler JA, et al. Effects of oral potassium on blood pressure: meta-analysis of randomized controlled clinical trials. JAMA. 1997;277:1624–1632. Thirty-three randomised trials (2,609 participants) in which potassium was the only difference between arms: pooled systolic −3.11 mmHg (95% CI −4.31 to −1.91) and diastolic −1.97 after excluding one trial with an extreme effect. In hypertensive participants the fall was larger (systolic −4.4, diastolic −2.5, as reported in secondary summaries of the paper); effects were enhanced with concurrent high sodium intake. Card the hypertensive figures as a subgroup, not the headline.
Yin X, Rodgers A, Perkovic A, et al. Effects of salt substitutes on clinical outcomes: a systematic review and meta-analysis. Heart. 2022. DOI 10.1136/heartjnl-2022-321332. Twenty-one randomised trials, 31,949 participants: systolic BP −4.61 mmHg (95% CI −6.07 to −3.14), diastolic −1.61. Total mortality RR 0.89 (0.85–0.94), cardiovascular mortality 0.87 (0.81–0.94), cardiovascular events 0.89 (0.85–0.94). Each 10% lower sodium-chloride proportion in the substitute brought 1.53 mmHg more systolic fall; the authors conclude blood-pressure lowering is the mechanism of the protection. Honest limit: 88–99% of the clinical-outcome data come from SSaSS itself, already carded on this shelf — this card's new contribution is pressure consistency across 19 trials and many geographies, not a second outcome win.
The question: Does vitamin E help — liver, prostate, or anything else — and at what cost?
The balance of the evidence: Vitamin E improves liver histology in nondiabetic NASH/MASH (43% vs 19% in PIVENS; 29.3% vs 14.1% at 300 mg in MASH) without improving fibrosis — but the same vitamin, at 400 IU daily for prevention in healthy men, raised prostate cancer (HR 1.17). Benefit is disease-specific and biopsy-deep; harm is prevention-dose-specific. Neither generalizes to the other. On dose, the 2026 VEDS trial found 200 IU/day matched 800 IU/day for ALT reduction over 24 weeks with no safety signal — if vitamin E is used, the lowest effective dose has the best-supported risk position.
Editor’s note · Oct 24, 2026 — Restored the same day it was paused, after the founder lifted the pause: every card here is published material with its source attached.
The question: Does psyllium supplementation improve lipid profiles in adults?
The balance of the evidence: Three LDL sources, one consistent direction — Gholami 2025 pooled LDL −8.55 mg/dL, Anderson 2000 pooled −7% vs placebo, and Anderson’s 26-week trial −6.7% — but heterogeneity is very high (I² 88% in Gholami), and lipid changes are not cardiovascular events: a surrogate win, not an outcome win. Bonus side fact: psyllium also lowered fasting glucose (−37.0 mg/dL) and HbA1c (−0.97%) in treated type 2 diabetes (Gibb 2015) — noted here only as a bonus; the full glycemic evidence is reserved for its own shelf.
Editor’s note · Oct 24, 2026 — Restored the same day it was paused, after the founder lifted the pause: the card here is published material with its source attached.
The question: Does glucose variability predict ICU death — and does diabetes change that relationship?
The balance of the evidence: Variability tracks death in patients without diabetes in the two big cohorts (Sechterberger top quartile OR 1.69; Krinsley threefold crude gap at CV >40%) and in influenza (HR 1.34 per 10 points) — but the diabetes interaction is never significant (Fluit p=0.25; Krinsley’s adjusted association absent in diabetes), and hypoglycemia predicts death in both groups (ORs 2.5/4.2; NICE-SUGAR HRs 1.41/2.10). Variability is a risk marker, sharpest without diabetes; it is not shown to be a treatment target, and diabetes does not cleanly modify it.
Editor’s note · Oct 24, 2026 — Deposit #24; structure decided by the founder Oct 24, 2026: GV stands as its own shelf rather than as the mechanism section of Shelf #17. Finfer stays Tier 3 pending the PDF pull. Hypoglycemia and variability stay separate exposures.
The question: Does vitamin E 400 IU/day raise prostate cancer risk in healthy men?
The balance of the evidence: SELECT’s harm arrived in two acts: the 2009 primary report showed no prevention benefit and a nonsignificant vitamin E trend (473 vs 416 cases, HR 1.13), and the supplements were stopped early for futility; extended follow-up made the harm significant — 620 vs 529 cases, HR 1.17, about 1.6 extra cancers per 1,000 person-years (Klein 2011). The harm is prevention-dose-specific: the same vitamin at treatment doses improves liver histology in MASH without this signal.
✓ LEVEL A — Founder-approved under the Level A rule, Oct 25, 2026.
Editor’s note · Oct 24, 2026 — Re-scoped the same day it was built, on the founder’s ‘Each one its own shelf’: #29 is now the SELECT shelf alone; Sanders is Shelf #30, CARET is Shelf #31, and the SSaSS hyperkalemia check is Shelf #32. Expanded from one card to two on Oct 25, 2026 at the founder’s direction (the design call on the deliberate single-card harm shelves): the SELECT primary report (Lippman 2009) added as Card 1, so the shelf shows how the harm emerged across follow-up. Klein 2011 was already this shelf’s card and is unchanged as Card 2.
The question: Does a single annual 500,000-IU vitamin D dose prevent falls and fractures — or cause them?
The balance of the evidence: It caused them: falls up 15%, fractures up 26% in 2,256 older women. The finding belongs to the annual mega-dose alone and says nothing about daily replacement for deficiency.
✓ LEVEL A — Founder-approved under the Level A rule, Oct 25, 2026.
Editor’s note · Oct 24, 2026 — Split from Shelf #29 on the founder’s ‘Each one its own shelf’: every harm gets its own shelf.
The question: Does high-dose beta-carotene plus vitamin A prevent lung cancer in smokers?
The balance of the evidence: Twice tested, twice harmful: beta-carotene raised lung cancer 18% in 29,133 Finnish smokers (ATBC 1994), and the beta-carotene + vitamin A combination raised it 28% in 18,314 US smokers and asbestos-exposed workers (CARET 1996, stopped 21 months early). The harm belongs to high-dose supplements in high-risk lungs, not to carotenoids in food.
✓ LEVEL A — Founder-approved under the Level A rule, Oct 25, 2026.
Editor’s note · Oct 24, 2026 — Split from Shelf #29 on the founder’s ‘Each one its own shelf’: every harm gets its own shelf. Expanded from one card to two on Oct 25, 2026 at the founder’s direction (the design call on the deliberate single-card harm shelves): ATBC added as the corroborating trial. Shelves #30, #32 and #33 remain single-card by design.
The question: Does potassium-enriched salt raise the risk of serious hyperkalemia?
The balance of the evidence: Checked in 20,995 people over 4.74 years and not found: serious hyperkalemia events 3.35 vs 3.30 per 1,000 person-years (RR 1.04), while the same trial cut stroke, major cardiovascular events, and death. A feared harm, looked for properly, that did not appear.
✓ LEVEL A — Founder-approved under the Level A rule, Oct 25, 2026.
Editor’s note · Oct 24, 2026 — Split from Shelf #29 on the founder’s ‘Each one its own shelf’: every harm gets its own shelf.
The question: Does peppermint oil cause adverse events in IBS — and do they outweigh the benefit?
The balance of the evidence: In 10 trials of 1,030 patients, peppermint oil helped global IBS symptoms (RR 0.65, NNT 4) and pain (RR 0.76, NNT 7) — but any adverse event was more common (RR 1.57: 17.1% vs 12.1%), driven partly by reflux symptoms (RR 1.67), on very-low-certainty evidence. A modest benefit with a real, if uncertain, adverse-event cost.
Editor’s note · Oct 24, 2026 — The herbs-paper harm shelf, built on the founder’s ‘Same for herbs paper harm’: one harm, its own shelf. The peppermint benefit shelf (same paper, symptom outcomes) is a separate Monday vote.
The question: How much of the glucose your liver makes comes from new synthesis versus recycling — and what changes it in fasting, diabetes, and cancer?
The balance of the evidence: Across five small physiology studies, the method holds up — a single isotope plus mass isotopomer analysis measures gluconeogenesis, and the corrected production rate matches the tritium gold standard (r=0.86). The biology: after 40 hours of fasting, gluconeogenesis is 92% of glucose production; in diabetes, production runs higher (2.8 vs 1.9) because gluconeogenesis runs higher; in one cancer subgroup, gluconeogenesis supplies most of the glucose and tracks cortisol (r=0.96). The doses matter too: low-dose glucagon raises production only through glycogen breakdown, high-dose through both routes. All of it is small-n physiology — the shelf is a methods story with biological payoffs, not clinical outcomes.
Editor’s note · Oct 24, 2026 — The founder’s own glucose-production program, 1991–2000: five of the six papers carded. The 1999 review is not a card — it is the theoretical defense of the method against Landau’s critique, and it is cited here as the method’s source. Three of the five cards are the Katz–Tayek pair; all five are the founder’s program.
Not carded: Katz & Tayek 1999 (Am J Physiol 1999;277:E401–7; PMID 10484349) — a Review, the theoretical defense of the method against Landau’s critique; cited here as the method’s source.
The question: In cancer, why does the body burn glucose differently — and can feeding or hormones reverse it?
The balance of the evidence: Across eight small Clinical Research Center studies, cancer raises hepatic glucose production and blunts insulin action — worst in the most malnourished, where production hits 2.98 and tracks growth hormone (r=0.71) — while five days of 5-FU nudges production higher still, and the liver’s TPN injury tracks duration of feeding more than the lipid itself (though early lipid drives the AST rise). Growth hormone raises IGF-I threefold but fails to build protein overall; it works only in patients who aren’t yet severely malnourished. And the one survival signal is thin: four metabolic numbers predict survival with 59% accuracy — barely above a coin toss.
Editor’s note · Oct 24, 2026 — The founder’s own cancer-metabolism program, 1990–1997: eight human studies carded. The two TNF-alpha papers (1990, 1996) are rat studies and stay out of the human set, per the library’s rule. Shelf #12 (cancer cachexia, approved) stands untouched — this shelf is the metabolism behind it.
Not carded: Tayek 1996 (J Am Coll Nutr 1996;15:164–8; PMID 8778147) and Tayek & Brasel 1990 (Cancer Res 1990;50:2765–8; PMID 2328503) — both rat studies; the library’s human set excludes animal work.
The question: Do sulfonylureas lower glucose by making the liver produce less — even before insulin rises?
The balance of the evidence: Three small studies, one thread: a very low dose of glyburide cuts fasting glucose by cutting hepatic glucose production — 16% in healthy volunteers with insulin unchanged, 19% in people with impaired fasting glucose — and a full-dose trial shows 2.5 mg of glipizide added to metformin moves A1c and fasting glucose significantly in 122 patients. The honest limit: the glipizide trial’s abstract prints p-values without effect sizes, so the card can say it worked, not by how much.
Editor’s note · Oct 24, 2026 — The founder’s own diabetes-drug work, 1995–2005: three trials carded. The two 2018 reviews (fasting glucose goals; durability of oral agents) are not primary-study cards. The glyburide pair is the mechanistic core of this shelf — the same 20 µg/kg dose, the same liver effect, eight years apart.
Not carded: Tayek 2018, fasting glucose goals (PMID 31404422) and Tayek 2018, durability of oral diabetic medications (PMID 30370022) — both reviews, not primary-study cards.
The question: Does high-dose vitamin D prevent upper respiratory infection in children?
The balance of the evidence: The two child RCTs split — Urashima positive for influenza A specifically (RR 0.58), Aglipay null for all viral upper respiratory infections when extra dose is added on top of standard intake in replete toddlers; the 2017 IPD child stratum was strongly positive (OR 0.60) while the pooled children-only meta-analysis (Carboo) is null and imprecise. The signal may be real for influenza and for deficient children; it is not a general “vitamin D prevents colds in kids” result.
Editor’s note · Oct 25, 2026 — Expanded Oct 25, 2026 from one card to four under the one-card program. The evidence is genuinely mixed — the child RCTs split, the 2017 IPD child stratum is positive, and the children-only meta-analysis is null and imprecise; see the balance line.
The question: Does vitamin D help adults fight bladder infection — and does supplementation prevent urinary infection?
The balance of the evidence: In adults, low vitamin D tracks with more urinary infection — a 2019 meta-analysis puts the odds at 3.01 — but the link is observational, and the one trial that cut UTIs (Jorde, 18 vs 34 over five years) used self-reported outcomes as a secondary endpoint. The bladder mechanism is real in tissue (Hertting): vitamin D primes bladder cells to make cathelicidin on bacterial contact. Correcting deficiency is sensible care; preventing infection with vitamin D is still open.
Editor's note · Oct 24, 2026 — Restructured at the founder's direction: this shelf is now the adults shelf (Hertting + Deng + Jorde + Ali). The children evidence moved to Shelf #39.
The question: Does vitamin D help children fight bladder infection — and does supplementation prevent urinary infection in children?
The balance of the evidence: In children, low vitamin D tracks with more urinary infection — a 2023 meta-analysis of 13 studies finds levels about 8 ng/mL lower in children with UTI, and below 20 ng/mL the odds rise fivefold — but every study is observational, and the one small trial of supplementation found nothing. Correcting deficiency is sensible; preventing UTI with vitamin D is unproven in children.
Editor's note · Oct 24, 2026 — Split from Shelf #38 at the founder's direction: the children evidence gets its own shelf. Two cards — one meta-analysis, one null trial.
The question: Does glipizide XL, through its delayed (GITS) delivery in the gut, prevent or reduce hypoglycemia and weight gain with sulfonylureas?
The balance of the evidence: Glipizide GITS lowers glucose without weight gain — two randomized trials in 347 patients and two combination trials found no weight change — and glipizide carries less hypoglycemia than glyburide (a 2007 meta-analysis: 83% higher risk with glyburide than with other sulfonylureas including glipizide). What is not shown: no trial compares GITS head-to-head against immediate-release glipizide on hypoglycemia, so the delayed-delivery advantage over its own immediate-release form is a mechanism — smoother levels, less between-meal insulin — not a measured outcome.
Editor's note · Oct 24, 2026 — Built at the founder's direction around his own glipizide GITS trial (Feinglos 2005, re-carded from Shelf #36). The delayed-delivery advantage over immediate-release glipizide is a mechanism, not a measured outcome — no head-to-head trial exists.
The question: Does taking fish oil (omega-3) raise the rate of atrial fibrillation in humans?
The balance of the evidence: High-dose omega-3 raises AF risk — about 25% relatively across the trials, roughly 1 extra case per 70–125 people treated at 4 g a day — and the risk climbs with dose: 4 g clearly, 1.8 g borderline, 840 mg no signal. The same 4 g of icosapent ethyl that cut heart events 25% in REDUCE-IT raised AF hospitalization from 2.1% to 3.1% — yet stroke was still lower overall. EVAPORATE, the 80-patient plaque trial, reported no AFib signal because it was far too small to see one.
✓ LEVEL A — Founder-approved under the Level A rule, Oct 25, 2026.
Editor's note · Oct 24, 2026 — Built at the founder's direction, including EVAPORATE, the plaque trial he co-authored. No AFib events are reported in EVAPORATE's published results; the card says so rather than repeating the founder's recollection as fact. RESPECT-EPA (1.8 g icosapent ethyl, new AF 3.1% vs 1.6%) is a candidate card pending an abstract check. Card 7 reframed Oct 24 at the founder's direction to AFib-only: the plaque numbers are out, replaced by the mineral-oil caveat; the founder has written to Budoff for the AFib numbers.
Miyauchi K, Daida H, et al.; RESPECT-EPA Investigators. Randomized Trial for Evaluation in Secondary Prevention Efficacy of Combination Therapy — Statin and Eicosapentaenoic Acid (RESPECT-EPA). Circulation. 2024 (presented AHA 2022). 2,506 Japanese patients with chronic coronary disease on statins and a low EPA:arachidonic-acid ratio (<0.4) were randomized, open-label with masked endpoint assessment, to icosapent ethyl 1,800 mg/day or no additional treatment. The trial did not meet its primary endpoint: the composite cardiovascular outcome occurred in 10.9% vs 14.9% (HR 0.785, 95% CI 0.616–1.001; P = 0.055). Secondary composites ran lower, but a trial stands or falls on its primary endpoint — on that test, EPA did not prove a benefit, and this shelf claims none from it. What the trial did show significantly is the side effect that recurs across the EPA trials: new-onset atrial fibrillation in 3.1% on EPA vs 1.6% on control (P = 0.017). On this shelf, RESPECT-EPA is evidence about harm, not efficacy.
The question: Does adding pegfilgrastim (long-acting G-CSF) to standard care improve 90-day survival in severe alcohol-associated hepatitis?
The balance of the evidence: In the United States, adding pegfilgrastim to prednisolone did not improve 90-day survival — 73% vs 83% in a trial stopped early at 34 patients — and it moved nothing else either: kidney injury, encephalopathy, and infections were the same. That sits against a 2020 meta-analysis in which G-CSF looked life-saving in Asian trials (death OR 0.15) and possibly harmful in European ones (OR 1.89), with the authors refusing to recommend it anywhere. A negative trial, honestly reported, is still evidence — and this one is the founder's own.
Editor's note · Oct 24, 2026 — The founder's first-author phase II RCT, stopped early by COVID-19 at 34 of a planned larger enrollment. The Marot meta-analysis predates it; the shelf does not pretend otherwise. Candidate not carded: Gallaher 2026 network meta-analysis (35 studies, 5,045 patients; G-CSF the only treatment with a significant 90-day mortality benefit, RR 0.49 — but no effect in the low-risk-of-bias subgroup).
The question: Does oral L-arginine, taken in moderation, lower blood pressure in humans?
The balance of the evidence: Oral arginine lowers blood pressure — about 6 systolic and 3 diastolic across 22 trials — and the effect holds in healthy and hypertensive people alike. But it is modest, it needs at least 4 grams a day, it doesn't grow past 9 grams, and it fades: in the founder's own crossover, pressure fell within two hours and was back within an hour of stopping. The responder pattern runs through the whole story — only the people whose citrulline rose got the full metabolic effect — and the biggest drops of all came in a handful of dialysis patients starting at 171 systolic.
Editor's note · Oct 24, 2026 — Group C, expanded: the founder's arginine pair (Huynh 2002, Apostol 2003 — both ORAL, hourly dosing in GCRC stays, not IV as an earlier note said) plus the two oral-only meta-analyses and the renal-transplant pilot. The founder recalls testing whether arginine raised growth-hormone pulsatility and finding it didn't work: the desk record shows no GH effect (Huynh: no effect on C-peptide, insulin, or other hormones) and the Apostol abstract reports no GH outcome — the full text would settle it. "In moderation" is doing real work here: ≥4 g/day works, >9 g/day adds nothing.
The question: Can an anti-inflammatory, anti-oxidative oral nutrition supplement raise serum albumin in hypoalbuminemic maintenance hemodialysis patients?
The balance of the evidence: Supplements reliably raise albumin a little (+0.19 to +0.23 g/dL across the syntheses; +0.21 in AIONID), an anti-inflammatory drug alone does the same with CRP falling (Pakfetrat), and the one large trial with a mortality endpoint (FINE) found no survival gain from intensifying nutrition — patients whose prealbumin rose did better, but raising the number has never been shown to be what saves them. Albumin here is a marker that moves, not yet a lever proven to change outcomes.
Editor's note · Oct 24, 2026, updated Oct 25, 2026 — The shelf now covers dialysis nutrition beyond the AIONID supplement: pentoxifylline as an anti-inflammatory (Pakfetrat), the enteral and oral-protein supplementation syntheses (Stratton; Mah, Cochrane), and the FINE trial's mortality endpoint. The founder is a middle author on the AIONID pilot-feasibility trial (Rattanasompattikul et al., J Cachexia Sarcopenia Muscle 2013). Two-thirds of the AIONID patients had diabetes, and the albumin theme ties to Shelves #7 (albumin and coronary calcium), #14 (cortisol and albumin in sepsis), and #19 (low creatinine and mortality).
The question: In type 2 diabetes, how common is coronary plaque, and can icosapent ethyl regress it — or is the placebo doing the work?
The balance of the evidence: In type 2 diabetes, plaque is common but not universal — one in five screened patients had normal coronaries. On icosapent ethyl, plaque didn't just slow, it regressed and stabilized: low-attenuation plaque down 17% while placebo rose 109%, and the lipid-rich necrotic core shrank within 9 months. The open question is the placebo arm: the published comparison says mineral oil didn't drive the progression, but that comparison is post-hoc and small — which is why the founder is asking the author directly.
Editor's note · Oct 24, 2026 — Group I shelf: the founder's last two uncarded trials (STOP baseline analysis; EVAPORATE plaque-morphology biomarkers), plus the EVAPORATE final re-carded from Shelf #41 (counted once) and the Lakshmanan mineral-oil comparison — the published answer to the founder's question 2 to Budoff. The AFib question (question 1 to Budoff) still stands and lives on Shelf #41 Card 7. The STOP paper is a baseline/screening analysis; the semaglutide-vs-placebo plaque-progression results are not in it.
The question: What does the 2024 Endocrine Society guideline say about who should get vitamin D — and who shouldn’t be tested for it?
The balance of the evidence: Thirteen years of guidance trace one arc — aim high and test (Endocrine 2011: target above 30 ng/mL, 1,500–2,000 IU/day); the nutrition establishment demurring the same year (IOM: 20 ng/mL suffices, bone outcomes only); prevention policy unable to judge screening (USPSTF 2021: I statement); and the specialty society finally landing on empiric supplementation for four defined groups with no routine testing and no definable target level (Endocrine 2024). The shelf is the record of a field correcting itself.
Editor's note · Oct 24, 2026 — Group K, the last of the founder's Tayek groupings (A–K): a guideline card, not a trial card — the founder is author 14 of 18 on the 2024 Endocrine Society clinical practice guideline. Its "against empiric vitamin D in healthy adults under 75" sits alongside Shelf #4's weak adult respiratory signal (Jolliffe 2025: OR 0.94, P=0.057); its children recommendation sits alongside Shelf #37. "Empiric" here means above the Dietary Reference Intakes without testing.
The question: After weight loss, what tracks growth-hormone pulse size — insulin or leptin?
The balance of the evidence: The energy-balance seesaw is consistent across three decades — fasting multiplies GH production fivefold in two days (Hartman) and triples integrated GH over five (Ho); visceral fat and fasting insulin predict blunted GH in larger samples (Clasey, Makimura); and in the founder’s own weight-loss study it was insulin, not the fat hormone leptin, that tracked the pulses’ recovery. None of these small physiology studies can say whether raising GH by lowering insulin changes outcomes — they map the signal, not its clinical use.
Editor's note · Oct 24, 2026 — The founder's growth-hormone pulsatility paper (Manglik 1998, senior author Tayek): GH pulses track insulin, not leptin, after weight loss. This is the pulsatility work the founder recalled — not the arginine studies, where the GH question remains open.
The question: Does periconceptional folic acid prevent neural tube defects?
The balance of the evidence: Two randomized trials, two populations: 4 mg a day cut recurrence by 72% in women with a previous affected pregnancy, and 0.8 mg in a multivitamin eliminated first occurrences in the trial (0 vs 6). The 400–800 mcg a day recommendation is the public-health dose between them — lower than either trial dose, anchored by these two trials.
✓ LEVEL A — Founder-approved under the Level A rule, Oct 25, 2026.
Editor's note · Oct 25, 2026 — From the supplements manuscript (Tsai, Aquije, Demanes, Tayek; v7 Sep 29, 2026, unpublished working manuscript). Cards cite only the published trials, never the manuscript; the manuscript's Take-Home Point 2 (400–800 mcg/day before conception and during early pregnancy) is the organizing frame. Note the dose ladder: 4 mg for recurrence, 0.8 mg for first occurrence, 0.4–0.8 mg as the recommendation.
The question: Does the AREDS2 formulation slow progression to advanced age-related macular degeneration?
The balance of the evidence: The original AREDS formula's 25% reduction in progression stands; nothing added on top in AREDS2 helped further. AREDS2's real contribution is subtraction — beta-carotene out, because it raised lung cancer in former smokers, and lutein with zeaxanthin in.
✓ LEVEL A — Founder-approved under the Level A rule, Oct 25, 2026.
Editor's note · Oct 25, 2026 — From the supplements manuscript (Tsai, Aquije, Demanes, Tayek; v7 Sep 29, 2026, unpublished working manuscript). Cards cite only the published trials, never the manuscript; the manuscript's Take-Home Point 3 (AREDS2 formulation only for the appropriate stage of AMD after ophthalmologic evaluation) is the organizing frame. The primary AREDS2 result is a null for the additions — the shelf says so plainly, and the formula swap is carried as a secondary finding, not as a primary win.
The question: Does cranberry prevent recurrent urinary tract infection in women?
The balance of the evidence: A defined product at a defined dose — 500 mg a day of whole cranberry fruit powder — halved recurrence in one good trial. Across 50 trials of mixed products the average is about 30% fewer UTIs. Product and dose are the whole story: juice and mixed products vary, and the pooled number is an average over unlike products.
Editor's note · Oct 25, 2026 — From the supplements manuscript (Tsai, Aquije, Demanes, Tayek; v7 Sep 29, 2026, unpublished working manuscript). Cards cite only the published sources, never the manuscript; the manuscript's Take-Home Point 4 (500 mg/day of whole cranberry fruit powder) is the organizing frame. Card 2 (Stonehouse 2025) is a RE-CARD from Shelf #18 Card 2; Card 1 (Cochrane 2023) is new.
The question: Does creatine monohydrate help older adults — and what does it do to the creatinine?
The balance of the evidence: Creatine adds a small strength increment on top of resistance training in healthy older adults — g 0.31 — while muscle mass and physical function show no significant additional benefit. And it reliably raises serum creatinine while true kidney filtration stays put. Know both before you prescribe it or interpret the labs.
Editor's note · Oct 25, 2026 — From the supplements manuscript (Tsai, Aquije, Demanes, Tayek; v7 Sep 29, 2026, unpublished working manuscript). Cards cite only the published sources, never the manuscript. Card 2 is the shelf's safety half: the creatinine rise is a measurement artifact, not kidney injury — the distinction matters every time a creatinine comes back high in someone taking creatine. Chilibeck 2017 (creatine + training, +1.37 kg lean mass) stays on Shelf #18; these two 2026 cards are new.
The question: Does standardized red yeast rice prevent cardiovascular events?
The balance of the evidence: One hard-outcome trial in post-MI patients — 45% fewer coronary events — plus a modern LDL trial. But both are standardized products, and the supplement-market version is not the trial product: Xuezhikang is a prescription-grade extract in China, and over-the-counter red yeast rice varies in monacolin content.
Editor's note · Oct 25, 2026 — From the supplements manuscript (Tsai, Aquije, Demanes, Tayek; v7 Sep 29, 2026, unpublished working manuscript). Cards cite only the published trials, never the manuscript. Card 2 (Liu 2026, natto red yeast rice) is a RE-CARD from Shelf #18 Card 6; Card 1 (Lu 2008, Xuezhikang) is new. The Japanese beni-koji contamination outbreak (2024) concerns a different manufacturer's product and is not carded here — it has no stable denominator and is a product-safety matter, not a trial result.
The question: Does coenzyme Q10 improve outcomes in chronic heart failure?
The balance of the evidence: One trial says CoQ10 halves events in heart failure; everything around it says handle with care — the earlier literature was 395 patients of short-term surrogate data (ejection fraction +3.67%, Fotino 2013), and the pooled mortality benefit (RR 0.69, Lei & Liu 2017; Cochrane 2021: probably reduces mortality and hospitalisation) appears only when Q-SYMBIO is in the pool. The honest statement is not “CoQ10 works” but “one good trial, never replicated, carries the entire outcome claim.”
Editor's note · Oct 25, 2026 — From the supplements manuscript (Tsai, Aquije, Demanes, Tayek; v7 Sep 29, 2026, unpublished working manuscript). Card cites only the published trial, never the manuscript. This card is a RE-CARD from Shelf #18 Card 3; it is the only hard-outcome positive in the supplement set and has been unreplicated since 2014. The shelf now carries the Q-SYMBIO trial plus three context syntheses (Fotino 2013, Cochrane 2021, Lei & Liu 2017); no second supporting trial exists. The shelf remains HELD.
The question: Does oat beta-glucan lower LDL cholesterol?
The balance of the evidence: The pooled trials say about 10 mg/dL off LDL (0.25 mmol/L) at 3 grams a day or more; the newest feeding trial points the same way but doesn't reach significance on its own. A food, not a pill — the dose is a bowl of oats.
Editor's note · Oct 25, 2026 — From the supplements manuscript (Tsai, Aquije, Demanes, Tayek; v7 Sep 29, 2026, unpublished working manuscript). Cards cite only the published sources, never the manuscript. The shelf's weight is Whitehead's 28-trial pool; Stote 2026 is a small, recent, directionally consistent trial that does not stand alone. Units updated Oct 25, 2026 at the founder's direction: LDL in mg/dL first, the papers' mmol/L in parentheses (conversion: mmol/L × 38.67).
The question: Does alpha-lipoic acid ease diabetic neuropathy?
The balance of the evidence: Alpha-lipoic acid 600 mg eases neuropathic symptoms in five weeks, and the 2026 pool agrees on symptoms while the objective nerve measures stay flat. Symptom relief, not disease modification — and 600 mg is the dose; higher doses add side effects without added benefit.
Editor's note · Oct 25, 2026 — From the supplements manuscript (Tsai, Aquije, Demanes, Tayek; v7 Sep 29, 2026, unpublished working manuscript). Cards cite only the published sources, never the manuscript. SYDNEY 2's 600 mg dose is the sweet spot; the 1,200 mg and 1,800 mg arms added adverse effects without added benefit.
The question: Does routine calcium plus vitamin D prevent fractures in healthy adults?
The balance of the evidence: The biggest trial says no significant hip-fracture benefit and more kidney stones; the 69-trial pool says little to no clinically meaningful fracture effect. Routine calcium plus D for fracture prevention in healthy adults is a near-null with a real stone risk.

Editor's note · Oct 25, 2026 — From the supplements manuscript (Tsai, Aquije, Demanes, Tayek; v7 Sep 29, 2026, unpublished working manuscript). Cards cite only the published sources, never the manuscript. This is the "routine" shelf — institutionalized, osteoporotic, or otherwise high-risk populations are a different question; the shelf is about routine supplementation in generally healthy adults.
The question: What happens when zinc is taken far above the recommended intake?
The balance of the evidence: The guidance threshold is real and the clinical harm is documented — NIH puts the upper limit at 40 mg/day and warns that 50 mg/day or more for weeks blocks copper absorption; the denture-cream case series (Nations 2008; Hedera 2009) show the neurologic syndrome at extreme exposure, with improvement only mild after the zinc stops; and routine prescribing itself often crosses the line without monitoring (62% of audited prescriptions at copper-depleting doses, copper checked in 2 of 70 — Duncan 2015). High-dose zinc’s main verifiable effect is copper deficiency, preventable and partly irreversible.
Editor's note · Oct 25, 2026 — From the supplements manuscript (Tsai, Aquije, Demanes, Tayek; v7 Sep 29, 2026, unpublished working manuscript). This is a guidance card, not a trial card: the cited source is the NIH Office of Dietary Supplements fact sheet, which sets the tolerable upper intake level and the copper-interaction threshold. Tier 3 reflects the source type, not doubt about the numbers.
Case report, Jpn J Oral Maxillofac Surg. 2022;68(6) (J-STAGE). A 69-year-old woman with type C liver cirrhosis had taken zinc acetate hydrate (Nobelzin®) for six years to control hepatic encephalopathy. After surgery for mandibular gingival carcinoma, pancytopenia appeared on preoperative blood tests; bone marrow examination excluded myelodysplastic syndrome. Serum zinc was high at 135 µg/dL and serum copper profoundly low at 12 µg/dL. Copper supplementation and stopping the zinc restored her copper to the reference range and improved the leukopenia within about two months. Prescribed zinc, taken exactly as directed for years, can quietly empty the copper store.
Motooka R, Yamamoto S. Copper deficiency myelopathy probably caused by long-lasting daily excessive intake of zinc. Rinsho Shinkeigaku (Clinical Neurology). 2016;56(10):690–693. DOI 10.5692/clinicalneurol.cn-000926. A 39-year-old woman developed progressive lower-limb spasticity and sensory disturbance over a year, with gait failure; spinal MRI showed a dorsal-column T2 signal, and serum copper and ceruloplasmin were low — copper-deficiency myelopathy. Re-taking her history revealed the source: 15–20 oysters every day for more than five years. The authors note that a dietary route to zinc excess is rare. The zinc that depletes copper does not have to come from a pill bottle.
Nishime K, Kondo M, Saito K, et al. Zinc burden evokes copper deficiency in the hypoalbuminemic hemodialysis patients. Nutrients. 2020;12(2):577. PMID 32102170. In 65 Japanese hemodialysis patients and 67 controls, serum zinc and copper were inversely correlated, with a steeper slope in the dialysis group. The authors derived the point at which copper falls into the deficiency range: a serum zinc above 109.7 µg/dL corresponded to copper below 41.0 µg/dL. Their proposed safety ranges for hemodialysis patients: zinc 41.3–78.3 µg/dL, copper 66.5–96.5 µg/dL — with monthly zinc and copper checks after starting zinc acetate. Note too: 75% of the dialysis patients had zinc below 60 µg/dL, largely tracking low albumin — the same misreading that starts unnecessary zinc prescriptions.
The question: Can high-dose biotin falsify laboratory results?
The balance of the evidence: The FDA warning is not theoretical: a controlled human experiment shows a standard 10 mg/day supplement dose corrupts 39% of biotin-based assays within a week (TSH driven below range on one platform), and about 1 in 13 outpatients and emergency patients carry biotin at or above interference levels. The failure mode is a falsified result in a patient who never mentions the supplement.
Editor's note · Oct 25, 2026 — From the supplements manuscript (Tsai, Aquije, Demanes, Tayek; v7 Sep 29, 2026, unpublished working manuscript). This is a regulatory-warning card, not a trial card: the cited source is the FDA safety communications (2017, updated 2019). Tier 3 reflects the source type. The manuscript's own line is the point — high-dose biotin "can produce clinically misleading laboratory results, including falsely low troponin measurements." Expanded from one card to three on Oct 25, 2026 at the founder's direction under the one-card expansion program (Li 2017 for the mechanism; Katzman 2018 for prevalence).
The question: Does selenium prevent prostate cancer?
The balance of the evidence: Selenium doesn't prevent prostate cancer — and in men who already have enough, supplementing raises high-grade disease by about 90%. The supplement helps no one in SELECT and harms the replete. The vitamin E harm from the same trial lives on Shelf #29 (Klein 2011, HR 1.17).

Editor's note · Oct 25, 2026 — From the supplements manuscript (Tsai, Aquije, Demanes, Tayek; v7 Sep 29, 2026, unpublished working manuscript). Cards cite only the published sources, never the manuscript. Card 1 is the main SELECT result (Lippman 2009); Card 2 is the baseline-selenium interaction — the reason "more is better" fails here.
The question: Can high-dose vitamin B6 cause neuropathy?
The balance of the evidence: The story runs from gram-dose abuse in 1983 to a European limit of 12 mg a day in 2023. Dose and duration decide: grams injure in months, a few hundred milligrams over a year or two, and case reports reach toward 50 mg — and the mechanism is a paradox, the supplement form blocking the active form. No safe dose below 50 mg a day has been established by trial.
Editor's note · Oct 25, 2026 — From the supplements manuscript (Tsai, Aquije, Demanes, Tayek; v7 Sep 29, 2026, unpublished working manuscript). Cards cite only the published sources, never the manuscript. The van Hunsel paper was refused for Shelf #18 in October 2026's build — a harm signal did not fit #18's benefit-only question — and the founder asked for the B6 literature in full on Oct 25, 2026: the shelf was expanded from one card to five, adding the 1983 first description, the 1985 dose–duration series, the 2017 mechanism, and the 2023 European limit. Note the arc: every number here comes from case reports, case series, cell work, or a regulator's synthesis of them — there is no randomized trial of B6 neurotoxicity, and there never will be.
The question: Why do some infants' seizures stop only with vitamin B6 — and what does treatment change?
The balance of the evidence: A blocked step in lysine breakdown floods the body with a compound that chemically switches off active vitamin B6, so the brain starves for B6 while the diet is normal. Large-dose pyridoxine overrides the block and stops seizures no standard drug touches — but it does not undo the metabolites' other damage: most patients still have intellectual disability, which is why treatment now adds lysine restriction and starts before birth when the risk is known.
Editor's note · Oct 25, 2026 — Ordered by the founder as the second of three vitamin B6 shelves (Shelf #60: excess neuropathy; Shelf #62: deficiency neuropathy). The condition was first described by Hunt et al. in 1954 (Pediatrics 1954;13:140–145) — one infant whose intractable convulsions only pyridoxine controlled; that case is history, cited here rather than carded. Note the mechanism rhyme with Shelf #60: there, excess pyridoxine blocks the active form's enzymes; here, an inborn error produces a metabolite that inactivates the active form itself. Either way the nervous system ends up short of working B6.
The question: Can too little vitamin B6 damage peripheral nerves?
The balance of the evidence: Yes — and the proof is a drug: isoniazid switches B6 off, nerves fail, and pyridoxine switches it back on. On high-dose isoniazid without B6 protection about a third of patients developed neuropathy, and giving B6 reversed it; in dialysis patients today, isoniazid prevention still produces neuropathy in about 1 in 6, and raising the pyridoxine dose resolves most cases. The deficiency state is measurable and reversible — the failure mode is not checking the level.
Editor's note · Oct 25, 2026 — Ordered by the founder as the mirror image of Shelf #60 (too much B6); together with Shelf #61 (B6-dependent seizures) it completes a three-shelf B6 set. The founder's own case — a woman with a mononeuropathy and a very low B6 level whose neuropathy resolved on repletion — is this shelf's clinical motivation; it is unpublished and is not a card. The boundary of the shelf: B6 is not a treatment for neuropathy in general. In the randomized diabetic-neuropathy trial (Levin et al.), only 1 of 18 patients was actually B6-deficient, and pyridoxine did no better than placebo — deficiency must be present, or induced, for repletion to work.
The question: What happened when a mold toxin contaminated beni-kōji supplements in Japan in 2024?
The balance of the evidence: This shelf documents a manufacturing contamination failure, not a pharmacological harm of red yeast rice — the deaths and kidney injuries trace to puberulic acid from mold contamination of specific 2023 batches, not to monacolin K or to beni-kōji as an ingredient. It sits next to Shelf #52 (red yeast rice LDL evidence) as the product-safety record for the same ingredient class, and as a case study in the risks of a lightly regulated supplement category (Japan’s “foods with function claims”).
Editor’s note · Oct 25, 2026 — Built at the founder’s direction in the Table 3 harms review. Counts are stated confirmed-vs-suspected because investigation totals changed over time.
The question: What harm, if any, does oral Nigella sativa (black seed) cause at the doses used in trials?
The balance of the evidence: Across two decades of reviews and the trial record, no severe harm signal for oral Nigella sativa at customary doses (1–3 g/day seeds, 5 mL/day oil) has been found — the documented items are minor gastrointestinal effects, rare skin reactions (mostly topical), a hypoglycemia note in hepatitis C patients, and a CYP-interaction flag at 5 g/day. This shelf exists so the negative is on the record: examined, not overlooked.
Editor’s note · Oct 25, 2026 — Built at the founder’s direction in the Table 3 harms review, as a no-signal card set. This shelf is a deliberate negative record: the absence of a harm signal is documented here, not left as silence.
The question: Does glucosamine, with or without chondroitin, raise the INR in patients taking warfarin?
The balance of the evidence: In randomized trials glucosamine and chondroitin are as benign as placebo; the one consistent post-marketing signal is INR elevation in patients on warfarin — case-report grade and mechanism unknown, but noted by the FDA, WHO, and EFSA, and clinically actionable: a patient on warfarin who starts glucosamine needs INR monitoring. (Not carded: three liver-injury cases on multi-ingredient glucosamine products in the LiverTox record — the products contained other potentially hepatotoxic herbals and were never characterized, so attribution is not possible.)
Editor’s note · Oct 25, 2026 — Built at the founder’s direction in the Table 3 harms review.
The question: Can turmeric or curcumin supplements injure the liver — and is the injury tied to the modern high-absorption formulations?
The balance of the evidence: Culinary turmeric and plain curcumin show a flat adverse-event record in trials (pooled RR ~1.03) — the liver injury belongs to bioavailability-enhanced products (piperine combinations, phytosome and similar formulations engineered to defeat curcumin’s poor absorption). Three independent literatures converge: US DILIN clinical cases (10, one fatal), Italian phytovigilance (7 cases plus 23 in review; mandatory warning labels followed), and a US pathology series (11 cases). The injury is hepatocellular, appears 1–4 months in, and concentrates in HLA-B*35:01 carriers; NIH LiverTox now rates turmeric/curcumin a well-documented cause of clinically apparent liver injury, and Australia’s TGA issued a 2023 alert (9 assessable reports, one death). Rare, idiosyncratic, occasionally fatal — and invisible to the trial adverse-event pooling.
Editor’s note · Oct 25, 2026 — Built at the founder’s direction in the Table 3 harms review (Item 6). The companion Table 3 item, natto/nattokinase, showed trial adverse events equal to control and remains a one-line null inside its benefit card.
The question: Does selenium supplementation cause type 2 diabetes?
The balance of the evidence: Two randomized trials disagree. In the NPC trial’s secondary analysis, selenium raised new diabetes (HR 1.55), and the risk climbed with baseline selenium — highest tertile HR 2.70. In SELECT, nearly thirty times larger, the same 200 µg/day dose showed no significant increase (RR 1.07; extended follow-up 1.04). If the harm is real, it likely sits in people already selenium-replete — but the biggest trial, run in exactly such men, is null. This shelf records a disagreement, not a verdict.
✓ LEVEL A — Founder-approved under the Level A rule, Oct 25, 2026.
Editor’s note · Oct 25, 2026 — Shelved at the founder’s direction after the Table 3 harms review, because the product and the harm differ from Shelf #29’s vitamin E story; the founder chose to shelve the disagreement itself rather than keep holding it. Thompson 2016 (Selenium & Celecoxib Trial) leans Stranges’ way (HR 1.25 overall; 2.21 in men ≥63) and is filed in the Table 3 review record, uncarded. Selenium’s prostate-cancer story stays on Shelf #59.

ICD-10: E11.9 Type 2 diabetes mellitus without complications · ICD-11: 5A11 Type 2 diabetes mellitus
The balance of the evidence: Three large trials point the same way on the composite, but the wins differ: empagliflozin’s is mortality, dapagliflozin’s is heart-failure hospitalization with a null MACE result, and canagliflozin carries an amputation signal the others do not.

The balance of the evidence: Three positive outcome trials, three different drivers: liraglutide’s win is cardiovascular death, semaglutide’s is nonfatal MI and stroke with a retinopathy caution attached, and dulaglutide’s is stroke in the broadest, mostly primary-prevention population.

ICD-10: E11.9 Type 2 diabetes mellitus without complications · ICD-11: 5A11 Type 2 diabetes mellitus
The balance of the evidence: Under the ADA’s own Level A wording, the GLP-1 benefit is agent-specific, not class-wide. Beyond the three trials on Shelf #71, three more agents cleared the superiority bar: albiglutide (HR 0.78, a drug no longer sold), efpeglenatide (HR 0.73, with a renal composite win), and oral semaglutide in SOUL (HR 0.86 over ~4 years). Lixisenatide and once-weekly exenatide did not clear it and are excluded from this shelf by the founder’s filter.

ICD-10: E11.22 Type 2 diabetes mellitus with diabetic chronic kidney disease · ICD-11: 5A11/GB61.Z Type 2 diabetes mellitus with chronic kidney disease (postcoordinated cluster)
The balance of the evidence: Two trials, one drug, complementary halves: in advanced diabetic kidney disease the kidney win leads (HR 0.82); in earlier disease the cardiovascular win leads (HR 0.87) and the kidney signal does not reach significance. Hyperkalemia is the recurring price in both — roughly double the placebo rate, though few patients had to stop.

The question: Does adding spironolactone to maximal ACE inhibitor / ARB therapy lower albuminuria in diabetic kidney disease — and has that ever been shown to change outcomes?
The balance of the evidence: The albuminuria effect is real and reproducible — about a third lower, on top of maximal RAS blockade, within weeks, and not explained by blood pressure. But every positive trial is small, short, and surrogate-only; the one large hard-outcome trial, in mostly non-albuminuric stage 3b CKD, found no cardiovascular benefit and two of three patients stopped the drug inside six months. A marker that moves, at a tolerability price.

The question: Do GLP-1 receptor agonists protect the kidney in type 2 diabetes with chronic kidney disease?
The balance of the evidence: FLOW gives the class its dedicated kidney-outcome win — kidney failure, halved eGFR, and death in one composite, with cardiovascular and all-cause mortality benefits attached. AWARD-7 is the supporting act: against insulin in stage 3–4 CKD, dulaglutide matched glucose control, slowed eGFR decline, and caused far less hypoglycemia. Whether GLP-1 benefit adds to SGLT2 therapy is the open question FLOW could not answer.

The question: Do thiazolidinediones lower albuminuria in diabetes — and on how much evidence?
The balance of the evidence: The albuminuria signal is consistent — roughly a fifth to a quarter lower — but it rests entirely on small, short trials and a surrogate endpoint. No thiazolidinedione has been tested in a kidney-outcome trial, and the class carries weight gain, fluid retention, and heart-failure baggage. This is the cluster’s thinnest shelf, and it says so.

The question: In a critically ill patient whose gut cannot meet calorie targets, how early should intravenous feeding start — within two days, or not before day 8?
The balance of the evidence: Withholding parenteral nutrition for a week beat starting it early — fewer infections, faster recovery, same mortality — in 4,640 adults and again in 1,440 children. The exception-shaped counterweight: when enteral feeding is truly impossible, early PN at modest targets did no harm and spared some ventilator days. ‘Late by default, early only when the gut is closed’ is what the trials support. (Panel position, 2016 SCCM/ASPEN: withhold supplemental PN until day 7–8 in patients who are not malnourished — attributed, for founder verification.)

The question: For early nutrition in critical illness, does feeding through the gut beat feeding through a vein — or the reverse?
The balance of the evidence: At trial scale, the route did not decide survival or infections — early parenteral nutrition was neither the villain of the old literature nor inferior in CALORIES. The one place route bit back: full-dose enteral feeding into a vasopressor-dependent gut caused more bowel ischemia. Route matters less than dose and timing; in shock, the gut sets the limit. (Panel position: enteral preferred over parenteral when the gut works — attributed, for founder verification.)

The question: Do high-dose glutamine and antioxidant supplements help critically ill patients with multiorgan failure?
The balance of the evidence: The supplement era’s flagship trial reversed the field: early high-dose glutamine in multiorgan failure did not just fail — mortality ran higher at every horizon. Antioxidants were simply null. What small positive trials had promised, one large blinded trial took away. (Panel position after REDOXS: parenteral glutamine not recommended for routine use in the critically ill — attributed, for founder verification.)

The question: Should gastric residuals keep being aspirated and measured in tube-fed patients — and at what volume should feeds be held?
The balance of the evidence: Checking gastric residuals did not prevent pneumonia, and loosening the limit from 200 to 500 mL changed nothing except the number of alarms. The monitored ritual mostly interrupted feeding. Two trials, one message: the stomach’s leftover volume is not the safety signal it was treated as. (Panel position, 2016: do not use gastric residual volumes in routine monitoring; if measured, do not hold feeds below 500 mL — attributed, for founder verification.)

The question: In critically ill patients, should insulin drive blood glucose down to 80–110 mg/dL — or is that the range where tight control turns harmful?
The balance of the evidence: One single-center trial made tight control (80–110 mg/dL) look lifesaving; every large multicenter test after it found no benefit or harm, and hypoglycemia every time. The 140–180 target in the guidelines is not a compromise — it is where the trial record actually lands.

Founder’s note (John Tayek, MD): This 140–180 mg/dL threshold was never itself tested as a target. It effectively mirrors the conventional arm of NICE-SUGAR (target 144–180) — the arm that won after the Leuven surgical-ICU trial’s suggestion that 80–110 might be better was tested at scale and tight control increased deaths. No trial has compared 140–180 against a more liberal range such as 180–220, particularly in patients without diabetes. My reading: for patients with diabetes, 140–180 is a sound threshold. For non-diabetics, whether it beats a higher range is still a question mark — treat the threshold as convention, not as trial-proven.

The question: Should tube feeds be delivered past the pylorus, into the small bowel — or is the stomach good enough?
The balance of the evidence: Two independent meta-analyses say feeding past the pylorus cuts pneumonia by about a third; the largest single trial found nothing; mortality never moves either way. The honest reading: fewer pneumonias on paper, no survival gain, and a harder tube to place — which is why the guidelines aim it at high aspiration risk and gastric intolerance rather than everyone.

The question: Should enteral nutrition start within 24–48 hours of injury or ICU admission — or can it wait?
The balance of the evidence: Start the gut early and infections fall and hospital stay shortens. A survival benefit is suggested by small-trial meta-analyses but has not been confirmed at scale — the large dose trials (EDEN, TARGET) and the timing network meta-analysis are null on mortality, and in established shock the enteral route carries a small bowel-ischaemia signal.

Founder’s comment — my own look back at EDEN (Torres JA, Pak Y, Tayek JA. Does early enteral calories in ARDS improve outcome? A retrospective evaluation of the EDEN trial. Clinical Nutrition Open Science 2023;49:130–139. DOI 10.1016/j.nutos.2023.04.003): EDEN randomized trophic vs full feeding and found no difference — but a quarter of the full-feeding arm never actually got fed. When we regrouped its 1,000 patients by calories actually delivered in the first 6 days, those who received ≥3,000 kcal (about 500 kcal/day) had a 90-day hospital mortality of 20% vs 26% below that line (adjusted HR 2.36, 95% CI 1.45–3.85, for the low-calorie group). This is retrospective and hypothesis-generating — the paper says so itself, and sicker patients may simply have been fed less. It is why this shelf keeps timing and dose apart: what arrives may matter more than what was prescribed.
The question: In patients with established ASCVD, does a statin — and driving LDL lower still — reduce deaths and further events?
MeSH: Coronary Disease · Myocardial Infarction · Anticholesteremic Agents · Hydroxymethylglutaryl-CoA Reductase Inhibitors · Cholesterol, LDL · Humans
ICD-10: I25.1 Atherosclerotic heart disease · ICD-11: BA52 Coronary atherosclerosis
The balance of the evidence: Four trials, three decades, one direction: after ASCVD, statins cut deaths (4S, HPS), and driving LDL lower with high-intensity therapy cuts events further (TNT, PROVE-IT). This is the trial record under the Class 1, Level A recommendation for high-intensity statin in secondary prevention.

The question: Should adults 40–75 with diabetes take a statin even when their LDL and their calculated risk look unremarkable?
MeSH: Diabetes Mellitus, Type 2 · Cardiovascular Diseases · Hydroxymethylglutaryl-CoA Reductase Inhibitors · Anticholesteremic Agents · Cholesterol, LDL · Humans
ICD-10: E11.9 Type 2 diabetes mellitus without complications · ICD-11: 5A11 Type 2 diabetes mellitus
The balance of the evidence: In diabetes, the benefit does not wait for a high LDL or a high risk score: CARDS enrolled patients with unremarkable cholesterol and still cut first events by more than a third, HPS found the same proportional gain with or without prior disease, and the trialists’ pooled analysis shows the per-mmol benefit in diabetes equals everyone else’s. That record is why the statin in diabetes 40–75 is Class 1, Level A regardless of calculated risk. (Panel position: 2018 AHA/ACC cholesterol guideline — attributed, for founder verification.)

The question: In people without prior cardiovascular disease, who gains from a statin — and how much does the choice of population change the size of the win?
MeSH: Hypercholesterolemia · Cardiovascular Diseases · Coronary Disease · Hydroxymethylglutaryl-CoA Reductase Inhibitors · Anticholesteremic Agents · Humans
ICD-10: E78.5 Hyperlipidemia, unspecified
The balance of the evidence: Primary prevention works, and the size of the win tracks how the patients were chosen: −31% in high-LDL men (WOSCOPS), −36% in hypertensive patients with risk factors (ASCOT-LLA), −44% in an inflammation-selected trial stopped early (JUPITER), −24% in unselected intermediate risk (HOPE-3). The relative benefit is consistent; the absolute benefit is the baseline risk — which is why the recommendation is written around risk, not cholesterol alone.

The question: Does blocking the renin-angiotensin system — ACE inhibitor, ARB, or ARNI — save lives in heart failure with reduced ejection fraction?
The balance of the evidence: Each generation of renin-angiotensin blockade beat the last standard: enalapril cut deaths in the sickest patients (CONSENSUS) and then in ordinary HFrEF (SOLVD), candesartan covered the ACE-intolerant (CHARM-Alternative), and adding neprilysin inhibition beat enalapril itself by a fifth (PARADIGM-HF). Four trials, four decades, same pathway — which is why an ARNI, ACE inhibitor, or ARB is Class 1, Level A for every patient with HFrEF.

The question: Do beta-blockers — once considered dangerous in heart failure — reduce mortality in HFrEF?
The balance of the evidence: Beta-blockers were once considered dangerous in heart failure; four randomized programs then showed the same ~35% mortality reduction, in mild disease and in the sickest patients, with three different molecules. When a feared drug class reproduces like that, it stops being controversial — bisoprolol, carvedilol, and metoprolol succinate are Class 1, Level A.

The question: Do mineralocorticoid receptor antagonists reduce mortality in heart failure with reduced ejection fraction — and what does the potassium guardrail cost?
The balance of the evidence: Three trials, three severity levels — post-MI, mild symptoms, severe disease — and the class cut deaths in all three, which is what Class 1, Level A means in practice. The guardrail is part of the evidence: every positive trial ran with potassium and renal monitoring and exclusions, and when real-world prescribing skipped the monitoring after RALES, hyperkalemia hospitalizations and deaths rose sharply (Juurlink 2004, observational — named in this note, not carded). The drug works; the surveillance is not optional. (Panel position: 2022 AHA/ACC/HFSA heart failure guideline — attributed, for founder verification.)

The question: Does a prophylactic implantable cardioverter-defibrillator reduce total mortality — and in whom?
The balance of the evidence: The ICD story is two true halves. In post-MI and mixed populations the device cut total mortality by roughly a quarter (MADIT-II, SCD-HeFT), earning Class 1, Level A. In modern nonischemic disease on contemporary therapy it halved sudden death and still did not significantly move total mortality (DANISH) — because the deaths it prevents are a smaller share of a better-treated total. The device works; the question the shelf leaves open is which patient, on today’s drugs, still has enough arrhythmic risk to gain.

The question: Do bisphosphonates and denosumab prevent fractures in postmenopausal osteoporosis — and how long should treatment continue?
The balance of the evidence: Three different antiresorptive strategies each cut vertebral fractures by half to two-thirds and hip fractures by about half (FIT, HORIZON, FREEDOM) — the fracture record is not in dispute. The live question FLEX answers is duration: after five years, women whose risk had fallen gained little from continuing except at the spine, which is why the guideline pairs a strong treat recommendation with reassessment and holidays rather than lifetime-by-default.

The question: For women at very high fracture risk, does building new bone beat slowing its loss — and at what cardiovascular price?
The balance of the evidence: For very high risk, building bone beats only slowing its loss: teriparatide cut vertebral fractures by two-thirds, and a year of romosozumab followed by an antiresorptive beat both placebo (FRAME) and alendronate itself (ARCH) — the only head-to-head anabolic win in the field. The same ARCH trial is why this shelf is not a simple endorsement: the cardiovascular imbalance, absent in FRAME’s placebo comparison, put a boxed warning on the drug and a risk screen in the guideline. Benefit and warning come from the same two trials, and the shelf keeps them together. (Panel position: Endocrine Society 2019 + 2020 update — attributed, for founder verification.)

The question: How far should systolic pressure be pushed — and in whom does pushing it prevent events rather than just add harm?
The balance of the evidence: Five large trials, one arc: SPRINT said lower is better but excluded diabetes and stroke; ACCORD-BP then missed in diabetes and froze the field for a decade; STEP, ESPRIT, and BPROAD — 33,000 patients, including the diabetics and stroke survivors SPRINT left out — all landed the same way. Intensive systolic control prevents events across every population actually tested; the price is hypotension, syncope, and electrolytes, paid openly on every card. (Panel position: ACC/AHA hypertension guideline — attributed, for founder verification.) The J-curve pair, 2002 and 2018: pushing systolic down has a diastolic floor — both analyses put the risk nadir at a diastolic of 70–84 mmHg and warn below 70 in coronary patients.

The question: Before asking how low to go — does treating blood pressure prevent events at all, does it still help past 80, and does the first drug chosen matter?
The balance of the evidence: Before targets came foundations: SHEP and Syst-Eur proved treating systolic pressure in older adults prevents strokes, HYVET proved it saves lives past 80, and ALLHAT — 33,000 patients — proved the first drug matters less than starting, with the thiazide never beaten. Every modern target argument, including Shelf #93’s, stands on these four. (Panel position: ACC/AHA hypertension guideline — attributed, for founder verification.)

ICD-10: I63.9 Cerebral infarction, unspecified · ICD-11: 8B11 Cerebral ischaemic stroke
The balance of the evidence: Six trials define life after a first stroke: an antiplatelet (clopidogrel at least matches aspirin — CAPRIE), a short burst of two antiplatelets when the event is minor and the clock is early (CHANCE and POINT — benefit front-loaded, bleeding the price of duration), a high-intensity statin even without coronary disease (SPARCL, with its small hemorrhagic excess shown), an LDL driven under 70 rather than merely treated (Treat Stroke to Target, HR 0.78), and blood-pressure lowering that prevents recurrence in normotensives too (PROGRESS).

The question: Tested the way drugs are tested — randomised, with heart attacks, strokes, and deaths as the endpoints — does a Mediterranean dietary pattern actually prevent cardiovascular events, in people who have never had one and in people who already have?
The balance of the evidence: Three randomized trials, three decades: Lyon showed a Mediterranean-type diet could prevent second events after infarction but was small and pre-statin; PREDIMED tested the pattern at scale in primary prevention and cut major events by about 30% — and its retraction and republication over randomization lapses is stated on its card, because the shelf keeps the correction with the claim; CORDIOPREV then showed the pattern beats a low-fat diet in patients with established coronary disease (HR 0.73).

The question: Does changing the salt itself — swapping regular salt for a potassium-enriched substitute, or eating less sodium for a few years — actually prevent strokes, cardiovascular events, and deaths, or does it only move the blood-pressure number? And what price, if any, does the added potassium carry?
The balance of the evidence: The salt shaker, trialed: SSaSS — 21,000 villagers — shows swapping regular salt for a potassium-enriched substitute prevents strokes and saves lives, with no hyperkalemia price in a population screened for kidney risk; TOHP shows a few years of sodium reduction still paying off a decade later; DECIDE-Diet confirms the blood-pressure mechanism in institutional kitchens, and is labeled the surrogate of the three.

The question: In atrial fibrillation at elevated risk of stroke, does anticoagulation actually prevent strokes and emboli — and can the direct oral anticoagulants match or beat warfarin, the drug that proved the principle, without its monitoring burden and its bleeding price?
MeSH: Atrial Fibrillation · Anticoagulants · Warfarin · Stroke · Embolism · Hemorrhage · Double-Blind Method · Humans
ICD-10: I48.91 Unspecified atrial fibrillation · ICD-11: BC81.3 Atrial fibrillation
The balance of the evidence: Warfarin proved the principle (EAFT: events halved after cerebral ischemia), then four trials in five years replaced it: dabigatran superior on strokes, rivaroxaban noninferior in the highest-risk cohort, apixaban superior on strokes, bleeding, and death together, edoxaban noninferior with less bleeding — every one of them kinder to the brain than warfarin on hemorrhagic stroke.

The question: In atrial fibrillation, is it better to restore and keep sinus rhythm, or simply to control the heart rate and let the rhythm be — and does the answer change if rhythm control starts early, if the rhythm is restored by ablation rather than drugs, or if the heart is failing?
The balance of the evidence: For twenty years the strategy question had one answer: AFFIRM and RACE said rhythm control buys nothing and costs hospitalizations. EAST-AFNET 4 reframed it — rhythm control delivered EARLY, within a year of diagnosis, cuts events by a fifth. Ablation’s own record is two-sided: CABANA’s intention-to-treat was null, CASTLE-AF’s failing-heart population won clearly. Timing and substrate, not the strategy label, decide.

The question: In peripheral artery disease, can antithrombotic therapy do better than a single antiplatelet drug — by blocking platelets harder, or by adding a small dose of anticoagulant alongside aspirin?
The balance of the evidence: PAD’s drug lesson comes in two parts: blocking platelets harder does nothing (EUCLID’s flat null), but blocking the clotting cascade a little — rivaroxaban 2.5 mg twice daily on top of aspirin — prevents heart attacks, strokes, acute limb ischemia, and amputations in stable disease (COMPASS) and after revascularization (VOYAGER), at a bleeding price both cards state.

The question: In stable coronary disease, does opening a narrowed artery with a stent prevent death or heart attack — or does it only relieve symptoms, and how much of that relief survives comparison with a placebo procedure?
MeSH: Coronary Disease · Percutaneous Coronary Intervention · Angina, Stable · Coronary Angiography · Myocardial Ischemia · Treatment Outcome · Humans
ICD-10: I25.1 Atherosclerotic heart disease · ICD-11: BA52 Coronary atherosclerosis
The balance of the evidence: Four trials discipline the catheter in stable disease: opening the artery does not prevent death or heart attack (COURAGE, ISCHEMIA), a sham procedure nearly matches it on exercise time in fully medicated patients (ORBITA) — and yet symptoms genuinely improve when PCI is tested against placebo in unmedicated patients (ORBITA-2).

ICD-10: E11.22 Type 2 diabetes mellitus with diabetic chronic kidney disease · ICD-11: 5A11/GB61.Z Type 2 diabetes mellitus with chronic kidney disease (postcoordinated cluster)
The balance of the evidence: Three decades, one axis: captopril halved renal failure in type 1 nephropathy (Lewis), losartan and irbesartan repeated it in type 2 (RENAAL, IDNT — with amlodipine proving it was never just blood pressure), and ONTARGET drew the ceiling — doubling the blockade adds harm, not protection.

MeSH: Aspirin · Platelet Aggregation Inhibitors · Hemorrhage · Aged · Double-Blind Method · Humans
The balance of the evidence: Three trials, 47,000 people, one verdict: in the statin era, aspirin’s primary-prevention benefit shrank to the size of its bleeding harm — in diabetes the two nearly cancel (ASCEND), in healthy elders there is no benefit and a mortality signal nobody has explained (ASPREE), and at moderate risk there is nothing to weigh at all (ARRIVE).

The question: Does intravenous vitamin C — alone, or in the vitamin C–thiamine–hydrocortisone cocktail — improve outcomes in sepsis, as a widely adopted before-and-after study promised?
The balance of the evidence: A before-and-after study launched a thousand protocols (Marik 2017 — retrospective, not randomized, and not carded here). The randomized trials then answered in sequence: no primary benefit in CITRIS-ALI, whose celebrated mortality difference was one secondary endpoint among many; no benefit for the full cocktail in VICTAS; and in LOVIT, the largest and cleanest trial, a harm signal.

The question: In people with prediabetes, can changing how they live — food, movement, weight — push back the day the diagnosis arrives, and by how long?
The balance of the evidence: Diabetes is progressive; nothing here cures or prevents it. What these trials show is delay, measured honestly: lifestyle pushed diagnosis back by the same ~58% on two continents (DPP, Finnish DPS), Da Qing timed the delay at about three and a half years and then watched it compound into fewer events and longer life over thirty years, and DPPOS shows the pushed-back clock keeps its lead even after the program ends. The founder’s arithmetic: roughly a pound lost, a point of glucose; ten pounds, ten points — and years. (Panel position: ADA Standards of Care — attributed, for founder verification.)
✓ LEVEL A — Founder-approved under the Level A rule, Oct 25, 2026.
Editor’s note · Oct 25, 2026 — The lifestyle delay trials, titled under the founder’s decree: the word is DELAY — diabetes is a progressive disease, and these trials push the diagnosis clock back rather than abolish the disease. Quarry: ADA Standards of Care, Level A (lifestyle intervention in prediabetes); primary studies only. Founder-approved Oct 25, 2026.
The question: Can a drug push back the day prediabetes becomes diabetes — and is the clock it moves the disease’s clock, or only the laboratory’s?
The balance of the evidence: Every glucose drug is also a clock drug. In ADOPT, rosiglitazone held monotherapy longest (15% failure at 5 years; the founder’s extrapolation reaches ~8 years to A1c 8%), canagliflozin’s slope runs to ~7, metformin’s to ~5, the DPP-4 agents and repaglinide to ~4 — a figure the founder himself questions — and glyburide, driving weight gain and insulin resistance, failed fastest: the clock can be wound forward as well as back. Durability is not destiny: rosiglitazone’s own harms are on its card. What none of these agents does is prevent diabetes — they delay its formal diagnosis, which is exactly what the founder’s decree says to call it. One caveat rides the whole shelf: a glucose-lowering drug can mask hyperglycemia rather than delay disease — hold the glucose down pharmacologically and the diagnosis is deferred whether or not the disease itself has slowed. Against pure masking stands the washout evidence: in TRIPOD (Card 6), protection persisted eight months after the drug was stopped, which argues true delay for the thiazolidinedione class. That tension is stated here, not resolved.
★ Founder’s comment (John Tayek, MD): “I can’t stand the idea of giving a medicine to delay the onset of diabetes — you’re kind of cheating the patients [out of] lifestyle, exercise, weight loss. And when they have diabetes, yes, give metformin — but that probably should be third line, after SGLT2 and GLP-1. Diabetes should be treated with the best drugs that reduce cardiovascular events — SGLT2 inhibitors and GLP-1s — and then metformin would be a reasonable third drug.”
Editor’s note · Oct 25, 2026 — Built at the founder’s direction: the DeFronzo glitazone delay trials (ACT NOW; the rosiglitazone-combination CANOE study) and the full set of 3-to-5-year monotherapy-in-prediabetes delay trials as Part A, with ADOPT durability as Part B. The year-lines on Card 9 are the founder’s own estimates and extrapolations, labeled as such on the card.

The question: Observational studies said hormone therapy protected women’s hearts. What did the randomized trials find — above all, about stroke?
The balance of the evidence: The observational claim that “hormones protect the heart” was refuted by randomization. HERS warned first, in 1998: no protection for women who already had coronary disease, more venous clots, and a pattern of early coronary harm. The Women’s Health Initiative then answered in healthy postmenopausal women — twice. Estrogen plus progestin increased stroke (HR 1.41) alongside coronary events, pulmonary embolism, and breast cancer, against fewer colorectal cancers and hip fractures, for a global index of net harm; and estrogen alone increased stroke too (HR 1.39), with no coronary benefit to set against it. Two randomized trials, two hormone regimens, one direction on stroke: up. The benefits that are real — hip fracture on both WHI cards, colorectal cancer on the combined card — are on the cards, at full weight. (Panel positions: Endocrine Society and NAMS statements — attributed, for founder verification.)
★ Founder’s comment (John Tayek, MD): “Anybody with a family history of stroke or high risk for stroke should not be offered this therapy — or consider not to offer this therapy.”
Editor’s note · Oct 25, 2026 — A harm shelf: the randomized record that reversed decades of observational reassurance about hormone therapy and the heart. It leads, at the founder’s direction, with the two Women’s Health Initiative trials — both showed increased stroke risk. HERS is Card 3 with its accurate profile: it showed NO significant stroke difference, and the card says so plainly. No LEVEL A stamp: this is a harm shelf. Founder-approved Oct 25, 2026.
The question: For decades the inflamed pancreas was “rested” by starvation. When should feeding start, by what route — and what happened the one time a trial added something extra?
The balance of the evidence: Feed early, by mouth when the patient can. The older pooled trials say starting enteral feeding early — within 24 hours where possible — beats feeding through a vein or waiting, on mortality, pancreatic infection, and organ failure (Card 2); the newest network ranking puts early oral feeding first of all strategies (Card 3). But the one large modern trial found that forcing a tube in within 24 hours did not beat simply offering food at 72 hours and tubing only those who could not eat (Card 1) — and in mild disease, eating immediately was safe and sent patients home sooner (Card 4). Timing matters more than the tube’s tip: a gastric tube performed like a jejunal one (Card 5). And more intervention is not more care — the one attempt to add something extra to early feeding in this disease killed people (PROPATRIA, Card 6).
Editor’s note · Oct 25, 2026 — Held at the founder’s direction until the stack carried more data, then approved to build from the completed stack. No LEVEL A stamp: the shelf mixes primary trials, two meta-analyses, and a harm trial. Founder-approved Oct 25, 2026.
The question: Does melatonin improve sleep onset, total sleep time, or sleep quality in primary sleep disorders?
The balance of the evidence: Melatonin shortens the time to fall asleep by minutes, on average — a real, small, replicated effect on a symptom, not a treatment for any disease.
Editor’s note · Oct 25, 2026 — Split from Shelf #18 (Herbs and dietary supplements) at the founder’s direction, on the ‘each one its own shelf’ principle; the card below is unchanged from its Shelf #18 text. No LEVEL A stamp. Founder-approved Oct 25, 2026.
The question: Does oral ginger improve nausea or vomiting during pregnancy?
The balance of the evidence: Ginger eases nausea in pregnancy in the trial evidence; symptom relief is the whole claim — no outcome data beyond it.
Editor’s note · Oct 25, 2026 — Split from Shelf #18 (Herbs and dietary supplements) at the founder’s direction, on the ‘each one its own shelf’ principle; the card below is unchanged from its Shelf #18 text. No LEVEL A stamp. Founder-approved Oct 25, 2026.
The question: Does peppermint oil relieve the pain and global symptoms of irritable bowel syndrome — and does the answer survive a large, rigorous trial with regulator-defined endpoints?
The balance of the evidence: Peppermint oil is the supplement shelf’s small-trial parable: a dozen small trials pool into a large, tidy benefit (RR 2.39) — and then the largest, most rigorous trial (PERSUADE) misses its primary endpoint while its secondaries nod yes. The effect on IBS pain and global symptoms is probably real and probably smaller than the pooled number; formulation and release site may decide who gets it. Symptom relief is the entire claim — there are no disease outcomes in IBS to win.
Editor’s note · Oct 25, 2026 — The benefit side of the peppermint oil literature, completing the split of Shelf #18’s supplement cards; the adverse-event side of peppermint oil is carded separately on Shelf #33 (Ingrosso 2022). No LEVEL A stamp: small trials, subjective symptom endpoints, and a missed primary endpoint in the largest trial. Founder-approved Oct 25, 2026.
The question: In septic shock, do corticosteroids save lives — or only shorten the shock?
MeSH: Shock, Septic · Hydrocortisone · Fludrocortisone · Anti-Inflammatory Agents · Double-Blind Method · Respiration, Artificial · Renal Replacement Therapy · Treatment Outcome · Humans
ICD-10: A41.9 Sepsis, unspecified organism · R65.21 Severe sepsis with septic shock · ICD-11: 1G41 Sepsis with septic shock
The balance of the evidence: Two mega-trials, one answer on speed, two answers on survival: hydrocortisone resolves shock faster in both; a mortality benefit appeared only when fludrocortisone was added in the sicker trial population.
The question: Does low-dose colchicine prevent cardiovascular events in coronary disease — and how far do the guidelines follow the two trials?
MeSH: Colchicine · Coronary Disease · Myocardial Infarction · Anti-Inflammatory Agents · Cardiovascular Diseases · Double-Blind Method · Intention to Treat Analysis · Proportional Hazards Models · Incidence · Humans
ICD-10: I25.9 Chronic ischemic heart disease, unspecified · I21.9 Acute myocardial infarction, unspecified · ICD-11: BA52 Coronary atherosclerosis · BA41 Acute myocardial infarction
The balance of the evidence: Two blinded trials say low-dose colchicine prevents cardiovascular events after MI and in chronic coronary disease; Europe grades the recommendation weaker than the US, and a non-cardiovascular death signal in one trial is unexplained.
The question: Cardiovascular prevention fails mostly at the pill bottle, not the prescription pad — what happens when the proven drugs are combined into a single tablet?
MeSH: Cardiovascular Diseases · Drug Combinations · Aspirin · Atorvastatin · Hydrochlorothiazide · Platelet Aggregation Inhibitors · Antihypertensive Agents · Myocardial Infarction · Secondary Prevention · Humans
ICD-10: I25.2 Old myocardial infarction · I25.9 Chronic ischemic heart disease, unspecified · ICD-11: BA50 Old myocardial infarction · BA5Z Chronic ischaemic heart disease, unspecified
The balance of the evidence: Across three randomized trials on three continents, putting proven cardiovascular medicines into one tablet cut major events by roughly a quarter to a third — not because the drugs are new, but because people actually take one pill: adherence is the active ingredient. The evidence is strongest after a heart attack (SECURE) and in pragmatic primary prevention (PolyIran); in the blinded primary-prevention trial (TIPS-3), the polypill alone was borderline and needed aspirin added to reach significance.
The question: Iron deficiency affects half of heart-failure patients. Does fixing it intravenously change outcomes — or only how patients feel?
MeSH: Heart Failure · Iron Deficiencies · Anemia, Iron-Deficiency · Ferric Compounds · Maltose · Hospitalization · Quality of Life · Stroke Volume · Ventricular Function, Left · Humans
ICD-10: I50.9 Heart failure, unspecified · E61.1 Iron deficiency · ICD-11: BD1Z Heart failure, unspecified · 3A00 Iron deficiency anaemia
LOINC: 2276-4 Ferritin
The balance of the evidence: Three large trials, one direction, no clean win: intravenous iron in iron-deficient heart failure makes people feel and function better — that part is proven — and probably keeps some out of hospital, but every outcomes trial has narrowly missed its primary endpoint and none has shown a mortality benefit. The guidelines recommend it for symptoms and quality of life; read the hospitalization claim as likely, not established, and the mortality claim as absent.
The question: Every ICU resuscitates with one of two fluids. Thirty years of habit says saline; physiology says balanced. What do 34,000 randomized patients say?
MeSH: Critical Illness · Fluid Therapy · Sodium Chloride · Saline Solution · Crystalloid Solutions · Isotonic Solutions · Intensive Care Units · Kidney Diseases · Humans
ICD-10: R57.9 Shock, unspecified
The balance of the evidence: One large single-center trial said balanced fluids win by a whisker on a kidney composite; the two big blinded multicentre trials found no mortality difference at all; pooling every patient suggests a small benefit — about one life per 250 treated, with roughly a 90% probability of being real — and a probable harm in traumatic brain injury, where saline remains the safer default. Balanced crystalloids are a reasonable default for most ICU patients; saline has not been convicted; and the size of the prize, if it exists, is small.
The question: How low can hemoglobin fall before transfusion helps more than it harms — and is the infarcting heart different?
MeSH: Anemia · Erythrocyte Transfusion · Blood Transfusion · Hemoglobins · Myocardial Infarction · Critical Care · Intensive Care Units · Humans
ICD-10: D64.9 Anemia, unspecified · D62 Acute posthemorrhagic anemia · ICD-11: 3A9Z Anaemias or other erythrocyte disorders, unspecified · 3A94 Acute posthaemorrhagic anaemia
LOINC: 718-7 Hemoglobin
The balance of the evidence: For a quarter-century the answer was simple: transfusing at a hemoglobin of 7 ties transfusing higher in the ICU, in septic shock, after hip fracture, and in cardiac surgery — and uses half the blood. MINT is the one trial that leans the other way: in acute myocardial infarction, every component favored the liberal strategy without reaching significance. Seven remains the rule almost everywhere; the acutely ischemic heart is the unresolved exception, and MINT is a trend demanding a second trial, not a verdict.
The question: Once the fluids are in and the pressors are running, what number should the nurse be chasing — and what does chasing more cost?
MeSH: Shock, Septic · Vasoconstrictor Agents · Blood Pressure · Hypotension · Atrial Fibrillation · Renal Replacement Therapy · Sepsis · Humans
ICD-10: A41.9 Sepsis, unspecified organism · R65.21 Severe sepsis with septic shock · ICD-11: 1G41 Sepsis with septic shock
The balance of the evidence: Aim at 65 and stop chasing more. Driving mean arterial pressure to 80–85 in septic shock saved no lives and bought atrial fibrillation; letting older patients run at 60–65 spent less vasopressor and killed no one extra — if anything, the adjusted analysis favored less drug. The Surviving Sepsis target of 65 is the rare guideline number attacked from both directions that held: higher does not help, lower does not hurt, and the kidney in chronic hypertension is the one voice still arguing for a little more.
The question: The emergency treatment of low sodium turns on two numbers everyone quotes and almost nobody can source: the bolus, and the ceiling.
MeSH: Hyponatremia · Saline Solution, Hypertonic · Infusions, Intravenous · Inappropriate ADH Syndrome · Sodium Chloride · Hospital Mortality · Hospitalization · Humans
ICD-10: E87.1 Hypo-osmolality and hyponatremia · ICD-11: 5C72 Hypo-osmolality or hyponatraemia
LOINC: 2951-2 Sodium
The balance of the evidence: The ceilings are real practice and the injury they guard against is real — but they were set by expert panels grading their own evidence D, and no randomized trial of correction speed has ever been run. The one trial we have says bolus and infusion are equally safe ways to give hypertonic saline. And across nearly 12,000 patients in the modern cohorts, the association runs against the fear: correcting slowly tracked with more deaths — about 32 extra per thousand versus rapid correction — while demyelination stayed rare at every speed. Treat the ceiling as a guardrail, not a cliff edge: below it, the documented danger is leaving a seizing, encephalopathic patient hyponatremic.
The question: Every trainee learns the speed limit for bringing high sodium down. Almost none learn that in adults, it was never measured.
MeSH: Hypernatremia · Sodium · Cohort Studies · Retrospective Studies · Critical Illness · Hospital Mortality · Aged · Humans
ICD-10: E87.0 Hyperosmolality and hypernatremia · ICD-11: 5C71 Hyperosmolality or hypernatraemia
LOINC: 2951-2 Sodium
The balance of the evidence: For high sodium, the famous limit — no faster than about ten points a day, lest the brain swell — has never been tested in an adult trial. It was borrowed from neonatal cases and expert opinion. In the two large modern adult cohorts, rapid correction produced not one attributed case of cerebral edema, while slow correction carried roughly double the adjusted odds of death. That gap is confounded — the sickest patients correct slowest — but the asymmetry is the finding: one side of the argument has more than 4,700 patients behind it; the other has a tradition.
The question: Hospital clot prevention is universal and automatic — what do the big trials actually buy, and what do they charge?
MeSH: Venous Thromboembolism · Venous Thrombosis · Pulmonary Embolism · Anticoagulants · Hemorrhage · Dalteparin · Enoxaparin · Rivaroxaban · Humans
ICD-10: I26.99 Other pulmonary embolism without acute cor pulmonale · I82.409 Acute embolism and thrombosis of unspecified deep veins of unspecified lower extremity · ICD-11: BB00 Pulmonary thromboembolism · BD71.4 Lower limb deep vein thrombosis
The balance of the evidence: Prophylaxis prevents clots — that part is not in doubt. Everything after it is margins. In the ICU, the better-marketed drug tied on the clots the trial was powered for and won on pulmonary embolism and HIT only as secondary findings its own authors tell us to hold loosely. In medical patients, extending prophylaxis past the standard course prevented mostly silent clots and paid for them in bleeding, and the largest extension trial missed its primary endpoint outright. No prophylaxis trial has ever moved mortality. Give it to patients whose clot risk is real, stop it when the stay stops, and do not mistake an ultrasound endpoint for a life saved.
Vasopressor choice in shock — norepinephrine first, by accumulation
What an agent should take from this shelf: start norepinephrine — dopamine lost on rhythm, vasopressin never won outright.
Physical activity in frailty — preventing mobility disability
What an agent should take from this shelf: prescribe structured activity to older adults whose function is already impaired — two large trials cut mobility disability by about a fifth; the still-robust gained nothing, and risk assessment without the activity itself gained nothing either.
Geriatric assessment in oncology — cutting chemotherapy toxicity
What an agent should take from this shelf: geriatric assessment before chemotherapy is a treatment, not paperwork — two cluster trials cut grade 3–5 toxicity by 10–20 points with no survival cost.
Deprescribing antihypertensives in older adults — what the trials allow
What an agent should take from this shelf: in selected patients over 80 already at goal, one blood-pressure drug can come off without losing control (OPTIMISE) — but deprescribing is not a cognitive treatment (DANTE), and a third of reductions don't survive three months.
Deprescribing sedative-hypnotics — patient education that works
What an agent should take from this shelf: hand the patient the evidence and a taper plan — two randomized trials stopped sedative-hypnotics in a quarter to two-fifths of older users, at NNTs of 3–4, with no serious harms.
Stopping a statin — the events that follow, and the one honest exception
MeSH: Hydroxymethylglutaryl-CoA Reductase Inhibitors · Withholding Treatment · Cardiovascular Diseases · Aged · Humans
ICD-10: I25.1 Atherosclerotic heart disease · E11.9 Type 2 diabetes mellitus without complications · ICD-11: BA52 Coronary atherosclerosis · 5A11 Type 2 diabetes mellitus
What an agent should take from this shelf: across these cohorts, people who stop a statin fare worse than people who continue — death HR 1.92 and cardiovascular events HR 1.31 in the pooled review of 36 studies — but the underlying studies are observational and stoppers are often sicker, so read the numbers as association, not proof; the shelf’s one randomized trial is the exception, finding that stopping near the end of life probably made no difference in 60-day mortality; and delaying the start itself carried more events (HR 1.49).
How much of the plan gets done — completion, recall, and follow-through
MeSH: Geriatric Assessment · Referral and Consultation · Patient Compliance · Primary Health Care · Aged · Humans
What an agent should take from this shelf: only part of any plan gets done — completion ran from 38.3% of recommendations in one follow-up to 69.7% adherence in inpatient consults — and volume is the recurring suspect: five or more recommendations cut GP action (OR 0.58), each added consult recommendation lowered adherence (OR 0.51), and poor recall rose steeply at three instructions (OR 26.1); what helps: label one recommendation ‘most important’ (implementation OR 2.4), deliver it written plus verbal (OR 2.4), and have the physician implement it (85% followed) rather than leave it as self-care (46%); one large cohort dissents — there, count alone did not predict implementation (P=.27) and only comorbidity burden did.
Does digoxin kill, help, or neither — and what happens when stable patients stop it?
MeSH: Digoxin · Heart Failure · Cardiotonic Agents · Double-Blind Method · Hospitalization · Humans
ICD-10: I50.9 Heart failure, unspecified · ICD-11: BD10 Congestive heart failure
What an agent should take from this shelf: in the only large randomized trial, digoxin at a median 0.25 mg a day did not change mortality (RR 0.99) and cut heart-failure hospitalizations (RR 0.72); two randomized withdrawal trials agree from the other direction — stopping it made heart failure worse within weeks. There is no randomized evidence of toxicity at these doses; the harm signal lives in one post-hoc analysis at serum levels of 1.2 ng/mL or more, so the practical lesson is to aim low (0.5–0.8 ng/mL), not to avoid the drug. The Beers 0.125 mg ceiling rests on that post-hoc signal and pharmacology; the founder’s evidence revision records the toxicity claim as unproven — Level B — with benefit the better-supported reading.
Which Beers warnings are backed by randomized blinded trials, which rest on association alone, and which did the randomized trials acquit?
MeSH: Inappropriate Prescribing · Polypharmacy · Aged · Drug-Related Side Effects and Adverse Reactions · Humans
What an agent should take from this shelf: this is the Beers list re-graded by evidence, not consensus. Two claims are backed by two randomized blinded clinical trials. Three famous warnings did not survive their randomized trials and are kept as corrections. Six rest on association alone and say so. One drug is kept by the founder’s decision, because its harm needs no trial. Four claims are held — neither convicted nor cleared, and the list admits it. One was examined and not carried. Where this list and the original disagree, the exhibits are printed on the entry — judge them yourself.
Kept by founder’s decision, in memory of Libby Zion, 18, who died in 1984 when meperidine was given on top of phenelzine — a fatal interaction from a drug whose toxic metabolite was already understood. Her death led New York to limit resident work hours, reforms that spread nationwide. A drug that can do this, with nothing to offer that safer opioids don’t, does not wait for a randomized trial.
Examined and not carried: H2-receptor blockers — the cognitive-harm accusation rested on a single unreplicated cohort (Boustani 2007, PMID 17661965). Its absence here is a decision, not an oversight.
The question: Does completing calories and protein early with supplemental parenteral nutrition improve survival in critical illness?
The balance of the evidence: The two biggest nutrition trials of the last fifteen years both favor patience: delaying parenteral completion by a week sped recovery rather than slowing it, doubling the protein dose did nothing, and the feeding route itself is a tolerance question, not a survival one. More, earlier, is not better.
The question: Does feeding hospital patients who are truly undernourished change survival — and how do you know which patients those are?
The balance of the evidence: Across five decades of trials, the pattern is consistent: feeding helps the genuinely undernourished and does nothing measurable for the well-nourished. One large modern RCT (EFFORT) and two meta-analyses put mortality roughly a quarter to a third lower with nutritional support in malnourished medical inpatients; the biggest null (FOOD) supplemented a population only 8% of whom were undernourished. Potter’s 2001 subgroup result — the shelf’s anchor — agrees with the Cochrane undernourished stratum, but on its own it is a subgroup of an overall-null trial that was powered for weight, not survival. Screen for undernutrition, feed the ones who have it, and deliver the supplement like a medicine — prescribed, scheduled, and observed.
★ Founder’s comment (John Tayek, MD): “Consider feeding patients over 60 whose BMI falls below the 5th percentile for their age — Potter’s ‘severely undernourished’ — with supplements prescribed like a medicine and given at medication rounds. That is where the mortality signal lives.”
