Meta analysis of 18 ivermectin RCTs with 2,282 patients showing faster viral clearance (dose and duration dependent), improved clinical recovery, and lower hospitalization and mortality. In six RCTs of moderate or severe infection, there was a 75% reduction in mortality, RR 0.25 [0.12-0.52], p
A sponsor reportedly required the conclusion of this paper to be changed against the wishes of the authors (to suggest that more trials should be done as opposed to the existing evidence being sufficient) [1, 2, 3]. Note that one of the 18 studies in this analysis has since been withdrawn (Elgazzar).

Effect extraction follows pre-specified rules
prioritizing more serious outcomes. For an individual study the most serious
outcome may have a smaller number of events and lower statistical signficance,
however this provides the strongest evidence for the most serious outcomes
when combining the results of many trials.
