risk of death, 92.0% lower, RR 0.08, p = 0.32, treatment 1 of 61 (1.6%), control 2 of 56 (3.6%), adjusted per study.
risk of ICU admission, 22.4% higher, RR 1.22, p = 1.00, treatment 4 of 61 (6.6%), control 3 of 56 (5.4%).
relative days alive and discharged from hospital within 14 days (inverse), 8.4% higher, RR 1.08, p = 0.36, treatment 61, control 56, adjusted per study.
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.
