Evaluation of endoscopic biliary stenting for obstructive jaundice caused by hepatocellular carcinoma

Figure 1 Comparison of the cumulative survival associated with the drainage effect between groups A and B. Overall cumulative survival in the 36 patients according to the drainage effect. The cumulative survival period was significantly higher in the successful drainage group patients compared with those in the unsuccessful drainage group (P < 0.0001) (Kaplan-Meier method; Log-Rank test).
