CONCLUSIONS
Treatment with ivermectin did not result in a lower incidence of medical admission to a hospital due to progression of Covid-19 or of prolonged emergency department observation among outpatients with an early diagnosis of Covid-19. (Funded by FastGrants and the Rainwater Charitable Foundation; TOGETHER ClinicalTrials.gov number, NCT04727424. opens in new tab.)
Discussion
The evidence supporting the role of ivermectin in the treatment of Covid-19 is inconsistent. At least three meta-analyses of ivermectin trials have strongly indicated a treatment benefit, and others have concluded that there was no benefit.7,8,18-20 Although the number of included trials involving outpatients varies among the meta-analyses, the overall number of events that occurred in our trial is larger than the number of all the combined events in these meta-analyses. The results of this trial will, therefore, reduce the effect size of the meta-analyses that have indicated any benefits. In addition, a reported trial of ivermectin treatment for Covid-19 was suspected of malfeasance and was withdrawn from publication,9 and other trials have been weakened by concerns about quality.8 A large collaboration of clinical trialists working on ivermectin treatment for Covid-19 has conducted a meta-analysis of trials and has concluded that ivermectin did not offer a treatment benefit when trials that were considered to be of moderate or better quality were examined.6 The WHO has concluded, on the basis of results obtained before our trial, that there existed only very-low-certainty evidence regarding ivermectin and thus recommended against the use of ivermectin for the treatment of patients with Covid-19 outside the clinical trial setting.21 The findings in our trial are consistent with these conclusions.
