Performance evaluation of the nomogram. (a) Time-dependent ROC curves for 1-year and 2-year overall survival (OS) predictions. (b) Calibration curves for 1-year and 2-year OS predictions. (c) Area under the curve (AUC) value and (d)concordance index (C-index) of the nomogram in predicting 1-year and 2-year OS in ten-fold cross-validation experiments. (e) Area under the curve (AUC) value and (f)concordance index (C-index) of the nomogram in predicting 1-year and 2-year OS in five-fold cross-validation experiments
