Figure 2 Time-dependent concordance index curves of the nomogram and Freiburg index of post-transjugular intrahepatic portosystemic shunt survival score for evaluating discrimination for post-transjugular intrahepatic portosystemic shunt severe hepatic encephalopathy over time. A: Training cohort; B: Internal validation cohort; C: External validation cohort. The modified model demonstrated superior performance compared to the Freiburg index of post-transjugular intrahepatic portosystemic shunt survival scoring system in predicting post-transjugular intrahepatic portosystemic shunt severe hepatic encephalopathy across all study cohorts. FIPS: Freiburg index of post-transjugular intrahepatic portosystemic shunt survival.
