The HCQ thing is a complete shit show, it has been politicized to the point where everyone pretty much just says whatever they want about it. It might be helpful as a prophylactic or with milder cases (when used in smaller doses). Other studies gave higher doses to severely ill patients and it did not help. Anyway, not trying to start another argument over this, but there is a vigorous argument still going on. A couple hundred professionals signed this open letter: https://zenodo.org/record/3871094
