risk of death, 34.3% lower, RR 0.66, p = 0.61, treatment 3 of 43 (7.0%), control 75 of 706 (10.6%).
This study is excluded in meta analysis: unadjusted results with no group details.
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.
