The authors of a recent study on hydroxychloroquine are retracting the paper.
The study, published last month by Lancet, found that the anti-malaria drug was ineffective when used to treat COVID-19 and potentially dangerous to patients. The authors say data from the study is now in question and they can "no longer vouch for the veracity of the primary data sources".
"We always aspire to perform our research in accordance with the highest ethical and professional guidelines," three of the authors wrote in their retraction for The Lancet. "We can never forget the responsibility we have as researchers to scrupulously ensure that we rely on data sources that adhere to our high standards. Based on this development, we can no longer vouch for the veracity of the primary data sources. Due to this unfortunate development, the authors request that the paper be retracted."
Another study published last week by the New England Journal of Medicine backed up claims that hydroxychloroquine is ineffective at treating COVID-19, but did not find it harmful.
"We deeply apologise to you, the editors, and the journal readership for any embarrassment or inconvenience that this may have caused," the authors added.
