Fig. 3From: A prediction model for permanent pacemaker implantation after transcatheter aortic valve replacementReceiver operating characteristics (ROC) curve in the derivation set (a), bootstrapped internal validation set (b), and external validation set (c). The AUROCs in the derivation, internal and external validation sets are 0.70 (95% CI 0.62–0.78), 0.70 (95% 0.62–0.79) and 0.71 (95% CI 0.43–0.99), respectivelyBack to article page
