Figure 3 The area under the curve values from the receiver operating characteristic analyses of the modified Clinical Outcomes of Malignant Biliary Obstruction-Biliary tract cancer Survival model, M stage, and carbohydrate antigen 19-9 level. A: 3-month overall survival (OS) of the training group; B: 6-month OS of the training group; C: 1-year OS of the training group; D: 3-month OS of the validation group; E: 6-month OS of the validation group; F: 1-year OS of the validation group. The blue curve represented the modified Clinical Outcomes of Malignant Biliary Obstruction-Biliary tract cancer Survival model, the orange curve represented M stage, and the green curve represented carbohydrate antigen 19-9 level. AUC: Area under the curve.
