The ROC curves for the models predicting pCR (A for the training set, B for the test set), pGR (C for the training set, D for the test set), and LNM (E for the training set, F for the test set). pCR, pathological complete response; pGR, pathological good response; LNM, lymph node metastasis; ROC, receiver operating characteristic; AUC, area under the curve.
