It measured how fast people felt better (\"time to sustained recovery\" — the first of 3 symptom-free days) and, secondarily, whether they ended up in hospital or dead. The answer was clear: ivermectin did not meaningfully speed recovery (hazard ratio 1.07, credible interval 0.96–1.17 — no benefit, if anything a hair the wrong way), and there were too few hospitalisations/deaths to say anything reliable about them. The headline finding is trustworthy, and here is the honest reason it is trustworthy even though the recovery endpoint is \"soft\" and self-reported: the trial was properly double-blinded, and blinding is exactly what protects a self-reported endpoint from wishful reporting — a blinded NULL is one of the hardest results to fake. So the soft-endpoint worry that flagged this paper did NOT turn out to be a fatal flaw. The real issues are smaller and sit off to the side: (1) the analysis population the authors used (\"everyone who took the drug\") is narrower than the population their own pre-registered protocol promised (\"everyone randomised, regardless of whether they took it\"), and the sibling higher-dose ivermectin paper from the same team was later formally corrected by JAMA for erroneously excluding 226 participants — a genuine integrity blemish, but one that did not change the negative conclusion; and (2) several authors disclose paid ties to makers of rival, patented COVID drugs — a conflict that points toward wanting a negative verdict on cheap off-patent ivermectin, which is worth naming, though there is no sign in the data that it distorted this particular blinded null.\n\n## Detailed findings\n\n**Finding 1 — The primary result is a robust null (this is the ground truth, not a defect).**\nTime to sustained recovery: HR 1.07 (95% credible interval 0.96–1.17), posterior probability of any benefit 0.91 [wearer web-search, unverified-wearer-supplied]. The interval straddles the null and the point estimate marginally favours placebo. Because the trial is randomised and double-blinded, this null is credible on its own terms.\n- INTEGRITY: n/a (this is the correct result, not a flaw). IMPACT: this IS the headline.\n\n**Finding 2 — Analysis population deviates from the pre-specified mITT (documented pre-specification deviation).**\nThe pre-registered protocol (ClinicalTrials.gov NCT04885530, Prot_SAP v12.0, p18, read via study_docs/load_pdf) defines the modified-ITT analysis as: \"All available data will be used to compare each study drug versus placebo control, **regardless of post-randomization adherence** to study protocols.\" The published paper instead analysed only participants who **received study drug** (817 ivermectin + 774 placebo = 1591). That is a narrower, more \"as-treated\" population than the protocol promised.\n- INTEGRITY: moderate — a published population narrower than the pre-specified one is exactly the kind of silent redefinition that must be flagged. IMPACT: low for THIS paper — the deviation appears applied symmetrically to both arms and no differential-exclusion signal for the 400 arm specifically surfaced; the direction of any bias is unclear and small. Registry appendix total (1800) vs analysed (1591) leaves a ~209 gap, but \"appendix\" bundles the shared concurrent placebo, so I do not attribute that gap — logged as an OPEN THREAD.\n\n**Finding 3 — Documented JAMA correction on the sibling higher-dose paper (first-class provenance finding, impact-low here).**\nJAMA published a formal correction, \"Errors in Results From Erroneous Exclusion of Participants in Analysis\" (jamanetwork fullarticle/2818993), with a companion notice by Naggie et al (JAMA 2024;331(21):1866-1867, DOI 10.1001/jama.2024.8723) [wearer web-search]. **226 participants were erroneously excluded** — but from the SIBLING ivermectin 600 µg/kg paper (JAMA 2023), not confirmed for this 400 paper. Critically, correcting it did **not** reverse the conclusion: the higher-dose result stayed null. The c19early.org critique additionally documents conflicting exclusion counts between the preprint and published 600 versions (drug-allergy 10 vs 7; warfarin 11 vs 4; recent-hospitalisation 9 vs 1) — a version-drift/data-integrity signal on the sibling.\n- INTEGRITY: serious in itself (an erroneous-exclusion correction is a real black mark on the platform's analysis pipeline). IMPACT: low — the correction and the original both land on \"no benefit,\" and the authors self-corrected rather than buried it. Advocacy framing (\"the trial hid a benefit\") is NOT supported: corrected and uncorrected results are both null.\n\n**Finding 4 — Hard secondary endpoint is underpowered → inconclusive, not \"proven safe-and-ineffective.\"**\nComposite hospitalisation/death/urgent-care by day 28: 34 (5.7%) ivermectin vs 36 (6.0%) placebo [wearer web-search]. Tool-computed (two_by_two, denominators ~596/600 reconstructed from the reported percentages — approximate): RR 0.95, 95% CI 0.60–1.50; ARR 0.3 percentage points; NNT ≈ 339. Deaths: 1 ivermectin, 0 placebo. The CI is wide and straddles the null.\n- INTEGRITY: fine (the paper does not over-claim this). IMPACT: matters for framing — any reading of \"ivermectin doesn't prevent hospitalisation/death\" is INCONCLUSIVE from this trial, not demonstrated. Absence of evidence, not evidence of absence.\n\n**Finding 5 — Symmetric conflict of interest, documented, pointing toward a negative verdict.**\nFunders: NIH/NCATS (grant U24TR001608), PCORI; steering committee included Operation Warp Speed/FDA/NIH. Drug supplied by Apotex, distributed by Belmar Pharmacy. Ivermectin is off-patent — the naive reading is \"no profit motive to inflate,\" i.e. low bias. But the symmetric check (Step 4) finds the opposite-direction interest IS present and disclosed: lead author Susanna Naggie discloses grants from **Gilead** and AbbVie, consulting fees from **Pardes Biosciences** and Silverback, scientific-advisor role + **stock options in Vir Biotechnology**, and BMS adjudication ties [wearer web-search, from the JAMA disclosure statement]. Gilead (remdesivir), Pardes (oral antiviral), Vir (sotrovimab) all make **competing patented COVID therapeutics** — a documented financial interest that cuts toward a negative verdict on a cheap rival. gather coi_lookup returned no dataset entry for Naggie (partial coverage), so this rests on the journal's own disclosure.\n- INTEGRITY: worth naming — this is precisely the symmetric-COI case the framework demands (a competing-product interest in a NEGATIVE result). IMPACT: low — the result is a blinded null with no hint of a suppressed positive signal (raw HR 1.07, not <1), and I INFER nothing about intent. Documented interest ≠ demonstrated influence.\n\n**Provenance caveats (stated as required):** The paper PDF itself failed to load (host reported \"not a PDF\"), so I could not read its metadata or run a table-level reconciliation census on the paper's own numbers — those come from the registry (tool), the pre-specified protocol/SAP (tool: load_pdf on ClinicalTrials.gov), and wearer web-search labelled \"unverified — wearer-supplied.\" Every arithmetic figure I state came from a tool (registry, two_by_two); reported HRs/percentages are the sources' own.\n\n## Iron-Man Summary\n\n- **The Claim:** A rigorous randomised trial shows ivermectin (400 µg/kg × 3 days) does not help outpatients with COVID-19.\n- **The Reality:** Correct. In 1591 randomised, double-blinded outpatients, ivermectin did not shorten self-reported recovery (HR 1.07, CrI 0.96–1.17), and the hard endpoint had too few events to judge (RR 0.95, CI 0.60–1.50). The published analysis population is narrower than the pre-registered mITT, and the sibling higher-dose paper needed a formal 226-participant exclusion correction — neither of which rescues a benefit.\n- **Design Score:** Strong (double-blind, placebo-controlled, concurrently-randomised platform RCT).\n- **Key Risk:** Soft self-reported primary endpoint (mitigated by blinding) + a documented pre-specification/exclusion deviation shared with a formally-corrected sibling.\n- **Integrity Check:** Conflicted — documented symmetric COI (authors tied to competing patented antivirals) and a documented erroneous-exclusion correction on the sibling paper; but self-corrected and impact-low on this null.\n- **Verdict:** **Supported by Data.** The negative conclusion holds; the soft-endpoint concern did not pan out as fatal because blinding protects a null. The real findings are integrity-flavoured and impact-low: a population deviation from protocol, a corrected sibling, and a symmetric COI worth naming.\n\n## NEXT LEADS\n\n- LEAD: id=10.1001/jama.2023.1650 | relation=methodological-sibling | why=Same team's higher-dose ivermectin (600 µg/kg) ACTIV-6 paper is the one JAMA formally corrected for 226 erroneously excluded participants — audit whether the correction fully reconciles and whether the same protocol-vs-published population deviation I found here recurs.\n- LEAD: id=10.1001/jama.2023.23363 | relation=same-funder | why=ACTIV-6 higher-dose fluvoxamine shares the funder, platform, soft self-reported recovery endpoint AND the received-drug analysis methodology; it is also in the fluvoxamine soft-endpoint family (cf.
