Hydroxychloroquine-Promoting COVID Study Retracted After 4 Years

Nature magazine reports that 'A study that stoked enthusiasm for the now-disproven idea that a cheap malaria drug can treat COVID-19 has been retracted — more than four-and-a-half years after it was published.'

Researchers had critiqued the controversial paper many times, raising concerns about its data quality and an unclear ethics-approval process. Its eventual withdrawal, on the grounds of concerns over ethical approval and doubts about the conduct of the research, marks the 28th retraction for co-author Didier Raoult, a French microbiologist, formerly at Marseille's Hospital-University Institute Mediterranean Infection (IHU), who shot to global prominence in the pandemic. French investigations found that he and the IHU had violated ethics-approval protocols in numerous studies, and Raoult has now retired.

The paper, which has received almost 3,400 citations according to the Web of Science database, is the highest-cited paper on COVID-19 to be retracted, and the second-most-cited retracted paper of any kind....
Because it contributed so much to the HCQ hype, 'the most important unintended effect of this study was to partially side-track and slow down the development of anti-COVID-19 drugs at a time when the need for effective treatments was critical', says Ole Søgaard, an infectious-disease physician at Aarhus University Hospital in Denmark, who was not involved with the work or its critiques. 'The study was clearly hastily conducted and did not adhere to common scientific and ethical standards....'
Three of the study's co-authors had asked to have their names removed from the paper, saying they had doubts about its methods, the retraction notice said.

Nature includes this quote from a scientific-integrity consultant in San Francisco, California. 'This paper should never have been published — or it should have been retracted immediately after its publication.'

'The report caught the eye of the celebrity doctor Mehmet Oz,' the Atlantic reported in April of 2020 (also noting that co-author Raoult 'has made news in recent years as a pan-disciplinary provocateur; he has questioned climate change and Darwinian evolution...')

And Nature points out that while the study claimed good results for the 20 patients treated with HCQ, six more HCQ-treated people in the study actually dropped out before it was finished. And of those six people, one died, while three more 'were transferred to an intensive-care unit.'
