Figure 7 Receiver operating characteristic and decision curve analysis for three models. A: Receiver operating characteristic (ROC) of clinical-radiological features on the training set; B: ROC of clinical-radiological features on the internal test set; C: ROC of clinical-radiological features on the external test set; D: Decision curve analysis on the training set; E: Decision curve analysis on the internal test set; F: Decision curve anal. ROC: Receiver operating characteristic; CI: Confidence interval; AUC: Area under the curve.
