NEW YORK (Reuters) - An influential medical journal article that found hydroxychloroquine increased the risk of death in COVID-19 patients was retracted on Thursday, adding to the controversy around a drug championed by U.S. President Donald Trump.
Three of the authors of the article retracted it, citing concerns about the quality and veracity of data in the study.
