risk of death, 6.3% higher, RR 1.06, p = 0.77, treatment 22 of 65 (33.8%), control 79 of 248 (31.9%), unadjusted.
This study is excluded in meta analysis: substantial unadjusted confounding by indication likely, excessive unadjusted differences between groups, 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.
