Since this is being repeated multiple times, quoting benmaraschino:
One of these "studies" is a 2-page Google Doc with no real data. Another is the discredited Raoult study, which is under investigation by the journal [1]. Another study cited is also by Raoult's team. The Brazil study (ref. 29) doesn't seem to have passed peer review (yet?) and has severe methodological flaws. Like the Raoult studies, the Brazil study was not randomized, but makes no attempt to control for confounding by indication or self-selection, such as with propensity score matching or similar methods commonly used in observational studies. The last study cited isn't a study, but an article from a local news station.
I believe Hydroxychroloquine is used as a prophylaxis in India and possibly other countries. Have there been any studies on that?
The death toll (CFR) in India is suspiciously lower than in the European states. Could it be because they're using Hydroxychroloquine more freely [0]? Though, that hasn't been without controversy [1].
>According to the ICMR study published in the Indian Journal of Medical Research (IJMR), consumption of four or more maintenance doses was associated with a significant decline (>80%) in the risk of Covid-19 infection among the ‘participants’. The study also found that there was no significant association between HCQ and adverse drug reactions.
