Comparison and evaluation of NRI-M model by predictive accuracy, discrimination and predictive error. A the ROC curve of NRI-M, NRI and MRI-Radiomics for all patients; B the ROC curve of NRI-M, NRI and MRI-Radiomics for early-stage patients. C the tAUC curve for all patients; D the tAUC curve for early-stage patients; E the prediction error curve for all patients; F the prediction error curve for early-stage patients. MRI, magnetic resonance imaging; NRI, nomogram-revised risk index; NRI-M, NRI plus multi-modal MRI radiomics signature; ROC, receiver operating characteristic; tAUC, time-dependent area under curve
