Receiver-operating characteristic (ROC) curves for the nomogram in the training (a) and validation sets (b). The predictive accuracy of the nomogram was positively correlated with the area under the curve (AUC). The AUC of the nomogram was 0.759 and 0.774 in the training and validation sets, respectively, indicating that the model had good discriminative ability. The specificity and sensitivity of the training set are 0.811 and 0.660, and the specificity and sensitivity of the validation set are 0.699 and 0.769.
