Serious integrity issue — Undisclosed financial conflict of interest, added only by later correction
In plain language
This is a meta-analysis that pooled three small trials (176 hospitalised COVID-19 patients in Iran) to ask whether the hepatitis-C drug pair sofosbuvir/daclatasvir helps people with COVID-19. It reports that the drug sped up recovery and cut deaths, and its abstract says the combination "improves survival and clinical recovery." The recovery finding is real but modest and comes from open-label (unblinded) trials, which inflate soft outcomes. The survival claim does not hold up: it rests on just 22 deaths total (5 of 92 vs 17 of 84), and the authors' own three sensitivity analyses each make the mortality benefit statistically non-significant — a fact the abstract and conclusion do not reflect. On top of that, the trials were run and analysed by the same people (not an independent synthesis), the work was funded by a treatment-access advocacy coalition, and the original paper failed to disclose that one author is a stockholder in a drug company (added only by a later correction). Bottom line: a hypothesis-generating signal on recovery, dressed up as proof of a survival benefit it cannot support.
Flags — what does not hold up
- high effect-not-robust — The headline mortality benefit is not robust; the authors' own sensitivity analyses erase it
integrity moderate · impact high
- high effect-not-robust — Overstatement: the abstract/conclusion assert a survival benefit the analysis does not support
integrity moderate · impact high
- moderate effect-not-robust — The recovery result is the robust one, but comes from unblinded trials
integrity clean · impact supports
- low coi-undisclosed — Undisclosed financial conflict of interest, added only by later correction
integrity serious · impact low
- moderate coi-undisclosed — Not an independent synthesis; advocacy funder
integrity moderate · impact moderate
- moderate conclusion-unsupported — Mixed evidence tiers
integrity moderate · impact moderate
- moderate coi-undisclosed — Senior-author provenance (context, not a numeric defect)
Next leads — where to look next
- 10.1093/ofid/ofab358 same-author
Same senior author (A. Hill) using the identical method (pooling small repurposed-drug trials under an advocacy funder); it was retracted for a fabricated included trial — the sharpest test of whether this author's pooling routinely outruns its inputs.
- 10.1093/jac/dkaa332 same-institution
Constituent trial (Kasgari et al) pooled here and co-authored by the meta-analysts; check whether its own pre-specified primary endpoint was met or whether a null trial is feeding the positive pool (F1/F6).
- 10.1093/jac/dkaa334 same-author
Constituent trial (Sadeghi et al) pooled here; queue notes a non-significant primary (p=0.076) framed as benefit — verify the individual-trial mortality contribution driving the fragile pooled estimate.
- 10.1093/jac/dkaa331 same-author
Third constituent trial (Eslami et al); the meta-analysis states it included non-randomised data, so audit this input's design and how much of the pooled recovery/mortality signal rests on it.
