Influential Hydroxychloroquine COVID-19 Study Retracted by Authors

An influential study measuring the efficacy and risks of the antimalarial drug hydroxychloroquine as a treatment for COVID-19 has been retracted at the request of its authors. It was published last month in prominent medical journal The Lancet.

The authors asked for the retraction because, after questions were raised about the data used in the research, independent auditors were denied access to the information required to verify that data.
