risk of death, 84.0% lower, RR 0.16, p < 0.001, treatment 35 of 317 (11.0%), control 197 of 328 (60.1%), adjusted per study.

risk of mechanical ventilation, 88.8% lower, RR 0.11, p < 0.001, treatment 4 of 317 (1.3%), control 37 of 328 (11.3%).

risk of disease progression, 77.8% lower, RR 0.22, p < 0.001, treatment 36 of 317 (11.4%), control 168 of 328 (51.2%).

risk of no recovery, 72.5% lower, RR 0.28, p < 0.001, treatment 46 of 317 (14.5%), control 173 of 328 (52.7%).

recovery time, 50.0% lower, relative time 0.50, treatment 317, control 328.

hospitalization time, 33.3% lower, relative time 0.67, treatment 317, control 328.

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.

Elimination of COVID-19 is a race against viral evolution. No treatment, vaccine, or intervention is 100% available and effective for all current and future variants. Denying the efficacy of any method increases the risk of COVID-19 becoming endemic; and increases mortality, morbidity, and collateral damage. We do not provide medical advice.
