Effect of initial stent position on patency of transjugular intrahepatic portosystemic shunt

Figure 2 Primary unassisted patency (A), recurrent variceal bleeding (B) and recurrent ascites (C) in four groups of patients with transjugular intrahepatic portosystemic shunt. A: The median shunt primary patency time was 5.2 mo in group A and 9.1 mo in group B (95%CI: 4.3-5.6, P = 0.013, log-rank test). The median shunt primary patency time was 8.3 mo in group C and 6.9 mo in group D (95%CI: 6.3-7.6, P = 0.025, log-rank test); B: The median time to recurrence of bleeding was 5.2 mo in group A and 7.4 mo in group B (95%CI: 3.2-8.5, P = 0.016, log-rank test). The median time to recurrence of bleeding was 8.7 mo in group C and 6.3 mo in group D (95%CI: 3.2-8.5, P = 0.011, log-rank test); C: The median time to recurrence of ascites was 5.9 mo in group A and 10.4 mo in group B (95%CI: 6.5-9.2, P = 0.007, log-rank test). The median time to recurrence of ascites was 9.1 mo in group C and 6.8 mo in group D (95%CI: 6.5-9.2, P = 0.009, log-rank test).
