Analysis of COVID-19 cases vs. widespread prophylactic use of ivermectin for parasitic infections showing significantly lower incidence of COVID-19 cases.
Hellwig et al., 11/28/2020, retrospective, ecological study, multiple countries, Africa, peer-reviewed, 2 authors, dosage 200μg/kg, dose varied, typically 150-200μg/kg.
risk of COVID-19 case, 78.0% lower, RR 0.22, p < 0.02, African countries, PCTI vs. no PCT, relative cases per capita.
risk of COVID-19 case, 80.0% lower, RR 0.20, p < 0.001, worldwide, PCTI vs. no PCT, relative cases per capita.
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.
