Forest plot of unadjusted odds ratios (ORs; 95% confidence intervals [CIs]) for access-related complications 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 6913 patients were analyzed for access-related complications, 3111 (45%) of whom underwent RA, and 3802 (55%) of whom underwent FA. Access-related complications were observed in 320 patients (4.6%). RA was associated with a reduction in access-related complications compared with FA (1.5% vs 7.2%, OR 0.25, 95% CI 0.15–0.39, P < 0.001), similarly in both randomized controlled trials (2.6% vs 7.1%, OR 0.36, 95% CI 0.24–0.54, P < 0.001) and cohorts (0.5% vs 7.2%, OR 0.09, 95% CI 0.03–0.29 P < 0.001).
