(A) ROC analysis of training group, the AUC was 0.73. (B) ROC analysis of training group, the AUC was 0.71. (C) Nomogram including nine methylation sites for predicting OS of bladder. Point of every methylated site was got according to the line drawn upward. The total points of the nine components of an individual patient calculated on the ‘Total Points’ downward, which corresponds to the probability of 1-, 2-, 3-year survival plotted below; AUC, area under curve; OS, overall survival; ROC, receiver operating characteristic.
