Figure 6 Time-dependent receiver operating characteristic curve analysis and decision curve analysis of the xTRM-W staging system and the 8^th edition American Joint Committee on Cancer tumor node metastasis staging system. A: Time-dependent receiver operating characteristic curve (ROC) analysis of the xTRM-W staging system in the training set; B: Time-dependent ROC analysis of the 8^th edition American Joint Committee on Cancer tumor node metastasis (AJCC TNM) staging system in the training set; C: Time-dependent ROC analysis of the xTRM-W staging system in the validation set; D: Time-dependent ROC analysis of the 8^th edition AJCC TNM staging system in the validation set; E: Decision curve analysis (DCA) of the xTRM-W staging system and the 8^th edition AJCC TNM staging system in the training set; F: DCA of the xTRM-W staging system and the 8^th edition AJCC TNM staging system in the validation set. ROC: Receiver operating characteristic curve; DCA: Decision curve analysis.
