tl;dr: A lot of ivermectin COVID studies are garbage. When you throw them out it seems like there might be a mild positive correlation but that depends on your methodology. But when you look at the bigger picture the decent positive studies often come from areas of the world where parasitic worms are prevalent. There is a specific parasitic worm Strongyloides stercoralis that multiplies out of control sometimes causing death when corticosteroids are taken - the exact kind of corticosteroids that improve survivability for those with COVID. For good quality studies ivermectin seems positive for COVID in areas with high parasitic worm infection rates and negative for areas without such infections, though more data is needed. This seems like a tidy answer because it shows everyone got part of the story wrong and it has a plausible mechanism of action which was previously lacking (ivermectin kills parasitic worms that suppress the immune system and/or multiply out of control when other drugs necessary to recover from CVOID are given).
