Nomogram construction and validation
REGRESSION
Based on multivariate Cox regression analysis, our nomogram was developed to predict OS in UTUC patients who received chemotherapy. In the nomogram depicted in Fig. Nomogram predicting 1-, 3-, and 5-year overall survival for UTUC patients treated with chemotherapy. Nomograms were built by using data from the training sets. RNU: Radical nephroureterectomy; PN/PU: Partial nephrectomy/ureterectomy; RN: Radical nephrectomy; LMR/LMD: Local Mass resection/destructionThe C index of our model is significantly higher than that of the TNM staging system (0.7108 VS 0.6723, ROC curves of the nomogram for predicting OS. The figure shows AUC of ROC in patients of training (ROC curves of the nomogram for OS compared with TNM staging. The figure shows AUC of ROC for 1 (Calibration plots for the nomogram. The figure shows calibration capacity for 1 (Comparison of DCA between the nomogram and 8th AJCC-TNM staging system for 1 (
