Development and validation of a predictive model for acute-on-chronic liver failure after transjugular intrahepatic portosystemic shunt

Figure 3 Receiver operating characteristic curves and the calibration plots of the model for predicting the incidence of acute-on-chronic liver failure within 1 year after transjugular intrahepatic portosystemic shunt. A: In the training cohort, the area under the receiver operating characteristic curve (AUC) of the model was 0.800 [95% confidence interval (95%CI): 0.731-0.868]; B: In the validation cohort, the AUC of the model was 0.761 (95%CI: 0.607-0.914); C and D: The calibration plots in the training and validation cohorts. The predicted probability of the model was plotted on the x-axis; the actual probability was plotted on the y-axis. An ideal calibration plot is indicated by a 45° diagonal line. AUC: Area under the receiver operating characteristic curve; 95%CI: 95% confidence interval.
