/med/fags, I want to ask you something: https://c19study.com/ links a lot of studies linking HCQ to positive outcomes for COVID patients, from early- to late-stage treatment (truth be told, late-stage treatment is low, but that's not the point). On the other hand, many people say it is uneffective against COVID (I assume with data to back up). How can we be sure of positive outcomes for drugs in this situation, considering that only treating patients with HCQ or placebo, no other treatment, may be unethical?
