I remember a preprint. I think it was comparing the recorery rate of

a) Ivermectin in the best hospital in the capital city of one of our most poor provinces in Argentina

b) The average in the same poor province

I don't expect too many problems with parasites there. They implicitly decided that the difference was ivermectin, not that the hospital is probably x10 better than the average of the province.

Doble blind randomized controlled group or it didn't happen.
