Nevertheless, despite all of the above, after publishing the contrary study by Drs. Mehra and Desai, the Lancet successfully lobbied the World Health Organization to suspend all clinical trials of HCQ. And, for added measure, France has banned its use.
So, how was it that the the Lancet article wound up contradicting the findings of HCQ’s many advocates? Was it because the study pertained to the treatment of hospitalized patients whose COVID-19 had progressed to the point where HCQ would no longer be effective? In other words, to paraphrase Dr. Risch’s abstract in the American Journal of Epidemiology, was the Mehra–Desai study based on “irrelevant evidence” about the use of HCQ to treat “inpatients” whose COVID-19 had reached the point where it was “very different” from the “early outpatient” phase of the disease?
On May 28, 2020, dozens of eminent “clinicians, medical researchers, statisticians and ethicists from [universities and medical centers] across the world” addressed an open letter to the study’s authors and the editor of the Lancet in which they raised “both methodological and data integrity concerns.” Here are some of the highlights:

Well, it turns out that the answers to those questions can’t be found in the study. As a matter of fact, the data on which the study is purportedly based are being seriously questioned by the scientific community.On May 28, 2020, dozens of eminent “clinicians, medical researchers, statisticians and ethicists from [universities and medical centers] across the world” addressed an open letter to the study’s authors and the editor of the Lancet in which they raised “both methodological and data integrity concerns.” Here are some of the highlights:
- The study’s authors did not indicate the “severity” of the disease being treated. Was it early on in the COVID-19 progression or late in the process? Similarly, they did not indicate the dosages of HCQ or CQ used.
- The authors have not adhered to “standard practices in the machine learning and statistics community. They have not released their code or data. There is no data/code sharing and availability statement in the paper.”
- There was no mention of the countries or hospitals from which the data were purportedly obtained, and the authors have denied requests for that information.
- The numbers of cases and deaths as well as the detailed data collection from Surgisphere-associated hospitals in Africa “seem unlikely.”
- Reported ratios of HCQ to CQ are “implausible.”
