Darquennes et al., 3/7/2021, retrospective, Belgium, Europe, peer-reviewed, 4 authors.
risk of death, 41.3% lower, RR 0.59, p = 0.06, treatment 93, control 257, odds ratio converted to relative risk, multivariable logistic regression, control prevalance approximated with overall prevalence.
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.
