The authors said the company that provided the data would not transfer the dataset for independent review and that they ‘can no longer vouch for (its) veracity’
NEW YORK — An influential medical journal article that found hydroxychloroquine increased the risk of death in COVID-19 patients was retracted on Thursday, adding to the controversy around a drug championed by U.S. President Donald Trump.
The anti-malarial drug has been controversial in part due to support from Trump, as well as implications of the study published in British medical journal the Lancet last month, which led several COVID-19 studies to be halted. The fourth author of the study, Dr. Sapan Desai, the chief executive of Surgisphere, declined to comment on the retraction.
Another study published in the New England Journal of Medicine that relied on Surgisphere data and shared the same lead author, Harvard Medical School Professor Mandeep Mehra, was also retracted for the same reason.
