risk of death, 6.2% higher, RR 1.06, p = 0.84, treatment 25 of 241 (10.4%), control 25 of 236 (10.6%), adjusted per study, odds ratio converted to relative risk, day 28.
risk of death, 51.0% higher, RR 1.51, p = 0.25, treatment 18 of 241 (7.5%), control 14 of 236 (5.9%), adjusted per study, odds ratio converted to relative risk, day 14.
risk of 7-point scale status, 3.1% higher, RR 1.03, p = 0.87, treatment 241, control 236, day 28, RR approximated with OR.
risk of 7-point scale status, 2.0% lower, RR 0.98, p = 0.91, treatment 241, control 236, day 14, RR approximated with OR.
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.
