Forest plot of unadjusted odds ratios (ORs; 95% confidence intervals [CIs]) for major bleeding after percutaneous coronary intervention in patients with acute coronary syndromes undergoing radial artery access (RA) compared with femoral artery access (FA). A total of 38,522 patients were analyzed for major bleeding, 10,709 of whom (28%) underwent RA and 28,976 (75%) underwent FA. Major bleeding was observed in a total of 1047 patients (2.7%). RA was associated with a reduction in major bleeding as compared with FA (1.4% vs 3.2%, OR 0.45, 95% CI 0.33–0.61; P < 0.001), similarly in both randomized controlled trials (1.0% vs 2.2%, OR 0.54, 95% CI 0.37–0.80, P = 0.002) and cohorts (1.8% vs 3.5%, OR 0.39, 95% CI 0.25–0.61, P < 0.001).
