Deep learning radiomics nomogram based on multi-regional features for predicting lymph node metastasis and prognosis in colorectal cancer

Figure 4 Comparative analysis of area under the receiver operating characteristic curve for the nine models. A: Comparison of the area under the receiver operating characteristic curve of the nine models in the training cohort; B: Comparison of the area under the receiver operating characteristic curve of the nine models in the internal validation cohort. ROC: Receiver operating characteristic; AUC: Area under the receiver operating characteristic curve; T: The intratumoral model; P3: The peritumoral-3mm model; TP3: The intra-peritumoral-3mm model; R: The radiomics model; DLR: The deep learning radiomics model; DLRR: Deep learning-radiomics integrated model.
