A major study on the effects of hydroxychloroquine on COVID-19 patients was retracted from a leading medical journal Thursday after doctors and scientists raised questions about the validity of the data.
The study had concluded patients taking the anti-malaria drug had a higher risk of death than those who were not taking the medication, leading some researchers to suspend their clinical trials.
The three authors of the study, led by Mandeep R. Mehra of Harvard Medical School and published in late May, retracted their study from the Lancet because independent peer reviewers could not access the data used for the analysis.
The source of the data was Surgisphere Corporation, which told peer reviewers it would not transfer the full dataset used for the study because it would violate client agreements and confidentiality requirements.
