risk of mechanical ventilation, 65.0% lower, RR 0.35, p = 0.16, treatment 3 of 95 (3.2%), control 6 of 66 (9.1%).
risk of ICU admission, 21.0% lower, RR 0.79, p = 0.78, treatment 8 of 95 (8.4%), control 7 of 66 (10.6%).
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.
