Overall survival model for patients undergoing elective transjugular intrahepatic portosystemic shunt (TIPS). Stepwise Cox model to assess independent predictors of death after TIPS implantation (n=234, death=94) and validation of the variables yielded by this stepwise Cox model in a non-stepwise analysis to reduce the number of missing cases (n=304, death=133)
