ROC analyses in ESCC patients. P values show the area under the ROC curves (AUC) of the three different models. Clinical characteristic include the statistically significant variables in multivariate analysis in Table 1. a ROC analyses of the prediction of DFS by the risk genotypes model, the clinical characteristics model, and the combined risk genotypes and clinical characteristics model. b ROC analyses of the prediction of DFS by the risk genotypes model, the TNM stage model, and the combined risk genotypes and TNM stage model. Clinical characteristic include the statistically significant variables in multivariate analysis in Table 1. c ROC analyses of the prediction of OS by the risk genotypes model, the clinical characteristics model, and the combined risk genotypes and clinical characteristics model. d ROC analyses of the prediction of OS by the risk genotypes model, the TNM stage model, and the combined risk genotypes and TNM stage model
