Machine learning prediction of hepatic encephalopathy for long-term survival after transjugular intrahepatic portosystemic shunt in acute variceal bleeding

Figure 5 Multivariate Cox regression analyses of overall survival. A: Cox regression model established with preoperative data; B: Cox regression model established with preoperative data and actual overt hepatic encephalopathy (OHE) status; C: Cox regression model established with preoperative data and predicted OHE value. Na⁺: Sodion; AIC: Akaike information criterion; TBIL: Total bilirubin; OHE: Overt hepatic encephalopathy.
