The area under the receiver operating characteristic curve (AUC) for the prediction nomogram. The ROC curve was measured to discriminate the performance of the VTE nomogram. The area under the receiver operating characteristic (ROC) curve (AUC) for the prediction nomogram was 0.822 (P < 0.001, 95%confidence interval:0.761–0.882), with a sensitivity of 0.839 and a specificity of 0.717
