Modified model incorporating sarcopenia and myosteatosis for predicting severe hepatic encephalopathy after transjugular intrahepatic portosystemic shunt: Multicenter study

Figure 3 Receiver operating characteristic curve of the nomogram and Freiburg index of post-transjugular intrahepatic portosystemic shunt survival score predicting post-transjugular intrahepatic portosystemic shunt severe hepatic encephalopathy at 3-month, 6-month, and 1-year. A-C: Training cohort; D-F: Internal validation cohort; G-I: External validation cohort. The modified model exhibited better performance than the Freiburg index of post-transjugular intrahepatic portosystemic shunt survival scoring system in predicting post-transjugular intrahepatic portosystemic shunt severe hepatic encephalopathy at all time points across all study cohorts. AUC: Area under the receiver operating characteristic curve; FIPS: Freiburg index of post-transjugular intrahepatic portosystemic shunt survival.
