The Lancet paper that halted global trials of hydroxychloroquine for Covid-19 because of fears of increased deaths has been retracted after a Guardian investigation found inconsistencies in the data.
The lead author, Prof Mandeep Mehra, from the Brigham and Women’s hospital in Boston, decided to ask the Lancet for the retraction because he could no longer vouch for the data’s accuracy.
