The receiver operating characteristic curves of the clinical, radiomics, and combined models in the training (a) and test (b) cohorts are displayed. It is plotted with the true positive rate (sensitivity) on the y-axis against the false positive rate (1-specifcity) on the x-axis. The diagonal line represents the performance of a random classifier. Rad radiomics model (KNN); AUC area under the curve
