Forest plot of unadjusted odds ratios (ORs; 95% confidence intervals [CIs]) for major adverse cardiovascular events (MACE) after percutaneous coronary intervention in patients with acute coronary syndromes undergoing radial artery access (RA) compared with femoral artery access (FA). A total of 38,520 patients were analyzed for MACE, 9544 (25%) of whom underwent RA and 28,976 (75%) underwent FA. MACE was observed in a total of 2608 patients (6.8%). RA was associated with a reduction in MACE as compared with FA (5.0% vs 7.3%, OR 0.70, 95% CI 0.57–0.85, P < 0.001). This significant reduction was only observed in cohort studies (6.4% vs 7.9%, OR 0.61, 95% CI 0.44–0.84, P < 0.01), however.
