Yep I spent a decent amount of time browsing around in pubmed and lancet looking for HCQ related research also. The point of it being already known to be effective to some degree in early stages of a SARs infection. Combined with SARs and Covid being the same family of virus with same cell attachment method. Means that HCQ was not just some accidental drug to test. They had a fairly good idea it would be effective. I think a time-line should reflect this. The medical community already knew they had a potential treatment for early stage infection.
