Forest plot of unadjusted odds ratios (ORs; 95% confidence intervals [CIs]) for major adverse cardiovascular events (MACE) after primary percutaneous coronary intervention in patients with ST-elevation myocardial infarction undergoing radial artery access (RA) compared with femoral artery access (FA). A total of 12,931 patients were analyzed for MACE, 5081 (39%) of whom underwent RA and 7850 (61%) of whom underwent FA. MACE was observed in a total of 751 patients (5.8%). RA was associated with a reduction in MACE as compared with FA (4.5% vs 7.1%, OR 0.55, 95% CI 0.45–0.68, P < 0.001), similarly in both randomized controlled trials (3.4% vs 6.6%, OR 0.67, 95% CI 0.5–0.90, P = 0.009) and cohorts (3.5% vs 6.6%, OR 0.46, 95% CI 0.34–0.63, P < 0.001).
