Construction and validation of the predictive model in elderly NPC patients. (A) Nomogram model established by prognostic index to estimate the 1-, 3- and 5-year survival possibility. (B) The calibration curves for validation of the nomogram. (C-E) The ROC curves comparing the accuracy of PI, RPA grouping and the other prognosis factors for predicting 1-, 3- and 5-year survival rate. NLR, neutrophil-to-lymphocyte ratio; RPA, recursive partitioning analysis; AUC, the area under the receiver operating characteristic curves; CI, confidence interval; PI, prognostic index; EBV, Epstein-barr virus; EBV DNApre, pre-treatment EBV DNA level. TPR, true positive rate; FPR, false positive rate
