You can access interactive meta analysis of 310 studies for HCQ[1] and 78 studies for ivermectin[2] below, it gets updated when new studies published. They also keep track of other treatments (in total 480[3]). But unfortunately only some of those treatments get media coverage like cannabidiol[4] even when they are neither the best performers nor best studied.

Definitely keep reading until you get to the "Worms" part of "The Analysis", which I think puts a pretty plausible explanation for why so many reputable studies show Ivermectin working against COVID as well as they did.
Obviously that's an issue for big pharma since they're not competitive when it comes to pure manufacturing of cheap drugs.
