" The
Lancet has reported coronavirus patients receiving hydroxychloroquine were more likely to die and experience dangerous irregular heartbeats."
From about a week later:
An influential study that found hydroxychloroquine increased the risk of death in COVID-19 patients has been withdrawn a week after it led to major trials being halted, adding to confusion about a malaria drug championed by U.S. President Donald Trump.

"The Lancet medical journal
pulled the study after three of its authors retracted it, citing concerns about the quality and veracity of data in it. The World Health Organization (WHO) will resume its hydroxychloroquine trials after pausing them in the wake of the study. Dozens of other trials have resumed or are in process.
The three authors said Surgisphere, the company that provided the data, would not transfer the dataset for an independent review and they
“can no longer vouch for the veracity of the primary data sources.”
The fourth author of the study, Dr. Sapan Desai, chief executive of Surgisphere, declined to comment on the retraction.
The Lancet said it “takes issues of scientific integrity extremely seriously” adding: “There are many outstanding questions about Surgisphere and the data that were allegedly included in this study”."

Some money quotes:
"Undisclosed is the fact that the two lead co-authors both have significant, relevant financial conflicts of interest that more than likely biased the reported findings
."
" Dr. Mandeep Mehra, the lead co-author is a director at Brigham & Women’s Hospital. Dr. Mehra and The Lancet failed to disclose that
Brigham Hospital has a partnership with Gilead and is currently conducting TWO trials testing Remdesivir, the prime competitor of hydroxychloroquine for the treatment of COVID-19, the focus of the study."
"The unvalidated database belongs to Surgisphere Corporation whose founder and CEO, is Dr. Sapan Desai, who is a lead co-author of the study. Dr. Desai has refused to disclose the data – for independent confirmatory review. In fact, he refuses to identify the participating hospitals, or even the countries."
"The alarming findings and serious negative impact of the Lancet report led numerous scientists around the globe to scrutinize the report in detail. That scrutiny by legitimate, independent scientists has led to many serious questions about the integrity of the study, the authenticity of the data, and the validity of the methods the authors used."
"The scientists question the evidence for claimed serious risks posed from the use of hydroxychloroquine in COVID-19 patients. Among the concerns raised by the scientists are the following:
- A range of gross deviations from standard research and clinical practices, such as: patients were prescribed inexplicably high daily doses of hydroxychloroquine –far higher than the FDA-recommended doses.
- There was no ethics review.
- The number of patients reportedly from Australia far exceeded the number of patients in the Australian government database;.
- Gross misrepresentation of the numbers of deaths in Australia.
- “Both the number of cases and deaths [the claimed 40% deaths in Africa], and the details provide seem unlikely.”
- Refusal to identify the hospitals that contributed patient data.
- The ratios of patients who received chloroquine (49 %) to those who received hydroxychloroquine (50% ) are implausible; in Australia chloroquine is not available without special government authorization."
