Effect of portal pressure gradient reduction on outcomes after transjugular intrahepatic portosystemic shunt in portal hypertension patients

Figure 4 Kaplan-Meier survival analysis for six outcomes between group A (portal pressure gradient reduction ≤ 50%) and group B (portal pressure gradient reduction > 50%) after propensity score matching. A: Rebleeding-free survival (P = 0.004); B: Shunt dysfunction-free survival (P = 0.002); C: Hepatic encephalopathy-free survival (P < 0.001); D: Hepatocellular carcinoma-free survival (P = 0.009); E: Liver failure-free survival (P = 0.003); F: Overall survival (P = 0.024). HE: Hepatic encephalopathy.
