Figure 2 Results from previous meta-analyses of RCTs, observational studies, and our propensity-score analyses for all our prespecified outcomes. For the meta-analyses of RCTs, we give the results from the most recent meta-analyses. Results are shown as ORs with 95% CIs. In cases for which the previous meta-analyses reported relative risks, we recalculated the OR by using the formula of Zhang and Yu.21RCT, Randomized clinical trial; OBS, observational study; PS, propensity score; RBC, red blood cell; OP, operation; IABP, intraaortic balloon pump; CI, confidence interval.
