Development and performance of the nomogram. Nomogram integrating the tumor location, N stage, RS, and DLS (A) Time-dependent ROC curves of the nomogram at 1-, 2-, and 3-year RFS for the training set (B) internal testing set (C) and external testing set (D) Calibration curves of the nomogram at 1-, 2-, and 3-year RFS for the training set (E) internal testing set (F) and external testing set (G) respectively. RS, radiomics score; DLS, deep learning score; RFS, recurrence-free survival; ROC, receiver operating characteristic; AUC, area under the curve.
