It is not an all-out, miracle cure but it definitely helps. Not trying to work anyone into a political fight, but I do firmly believe the US medical industry is doing active propaganda to prevent use of HCQ for Covid-19.
If you open the study, you'll see there are open-labeled non-randomized trials he is referencing.
It's been a handful of months since COVID-19 grasped the globe. Too early to take things as gospel. As we are finding out in this thread, these types of studies are open to bias and rife with mistakes or misinterpretations. If we are to take the desired lesson from this thread, it's that data surrounding these medical journals need to be highly scrutinized before we can take them in as evidence.

So in other words, unproven.
Researchers have withdrawn[1] studies that claimed much weaker statements than this.

The studies that the right wing news media and Trump were referring to back in March showed a one hundred percent cure rate.
Mainstream media sources in the USA were mainly warning not to obtain HCQ without a prescription (as several people did in various countries and killed themselves/spouse with overdoses). And also that people shouldn’t rashly expose themselves to the virus, believing the president and his political allies that they could be “100%” cured using HCQ. For instance, https://www.businessinsider.com/coronavirus-twitter-deletes-... “Twitter removed [. . .] In the tweet on Friday, Giuliani quoted conservative youth activist Charlie Kirk, who claimed that an unproven anti-malaria drug, hydroxychloroquine "in at least three international tests was found 100% effective in treating the coronavirus," according to screen shots of the message published by Mediate.”
HCQ continued to be used under emergency authorization in hospitals by doctors fighting the coronavirus, because it’s possible it somehow helps although it hasn’t been proven to work.
However, the media attempted to fight the spread of misinformation which claimed a 100% effective treatment was available, which was leading to issuing unneeded prescriptions for HCQ and a shortage for patients who actually needed the drug for other conditions. https://www.nytimes.com/2020/04/25/us/coronavirus-trump-chlo... “ And the nearly 32,000 prescriptions came from across the spectrum — rheumatologists, cardiologists, dermatologists, psychiatrists and even podiatrists, the data shows.”
