PARIS | The prestigious medical journal The Lancet has taken its distances with the study of the criticism she has published on the hydroxychloroquine, recognizing in a formal warning that “serious questions” existed about it.
The Lancet wishes to “alert readers to the fact that serious scientific questions have been brought to (his) attention” to the subject of this study, which is currently the subject of an audit initiated by its authors, says the journal.
This warning was issued Tuesday evening in the form of an “expression of concern” (” expression of concern “), the formal declaration used by scientific journals to indicate that a study is potentially problematic.
If an “expression of concern” is not as heavy of consequences as a withdrawal, pure and simple, it is all the same a nature as to cast doubt on scientific work.

These data emanate from Surgisphere, which presents itself as a society of analysis of health data, based in the United States.
The study has also been attacked with virulence by the defenders of the hydroxychloroquine, the first of which the French researcher Didier Raoult.
After having already called the study ” half-assed “, he believed that it had been done by ” nickel plated feet “, in a video put online on Tuesday.
For their part, the authors, Dr. Mandeep Mehra and his colleagues, defending their study.
“We are proud to contribute to the work on the COVID-19″ in this period of ” uncertainty “, had told AFP on may 29, one of them, Sapan Desai, owner of Surgisphere.
