ROC curves

(a) ROC curve for valve implantation depth for predicting postoperative LBBB or high-grade AVB, with AUC = 0.804, 95% CI: 0.666–0.942, P = 0.001, cutoff point according to Youden’s index of 4.30 mm, sensitivity of 0.667, and specificity of 0.864; (b) ROC curve for the angle of the aortic root for predicting postoperative LBBB or high-grade AVB, with AUC = 0.726, 95% CI: 0.570–0.882, P = 0.011, cutoff point according to Youden’s index of 59°, sensitivity of 0.714, and specificity of 0.773

AUC: area under the curve; AVB: atrioventricular block; LBBB: left bundle branch block; ROC: receiver operating characteristic
