RCT 254 very late stage (93% on oxygen, 17% in ICU at baseline) hospitalized patients in Saudi Arabia not showing significant differences with HCQ+favipiravir treatment. Only SaO2 < 94% patients were eligible, however the actual SaO2 of enrolled patients is not provided.

risk of death, 3.7% lower, RR 0.96, p = 0.91, treatment 14 of 125 (11.2%), control 15 of 129 (11.6%), 90 days.

risk of death, 28.6% lower, RR 0.71, p = 0.45, treatment 9 of 125 (7.2%), control 13 of 129 (10.1%), 28 days.

risk of death, 65.1% higher, RR 1.65, p = 0.68, treatment 8 of 125 (6.4%), control 5 of 129 (3.9%), 14 days.

risk of mechanical ventilation, 8.4% higher, RR 1.08, p = 0.78, treatment 21 of 125 (16.8%), control 20 of 129 (15.5%).

risk of ICU admission, 31.0% higher, RR 1.31, p = 0.24, treatment 33 of 125 (26.4%), control 26 of 129 (20.2%).

recovery time, 28.6% higher, relative time 1.29, p = 0.29, treatment 125, control 129.

hospitalization time, 12.5% higher, relative time 1.12, p = 0.42, treatment 125, control 129.

risk of no virological cure, 2.6% lower, RR 0.97, p = 0.75, treatment 100 of 125 (80.0%), control 106 of 129 (82.2%).

This study is excluded in meta analysis: very late stage, >50% on oxygen/ventilation at baseline.

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.
