Input (English): Question: Does new model for end stage liver disease improve prognostic capability after transjugular intrahepatic portosystemic shunt?
Answer: MELDNa performed better than MELD in predicting death or transplant after non-emergent TIPS, especially in patients with low MELD scores. A MELD score <or=18 can provide a false positive prognosis; a MELDNa score <or=15 provides a more accurate risk prediction.
Output (English): yes
