Figure 1 Kaplan-Meier analysis of metal stent patency rates and overall survival in the photodynamic therapy and control groups. A: Kaplan-Meier analysis of metal stent patency rates. The median stent patency was longer in the photodynamic therapy (PDT) group than in the control group (244 d vs 177 d; P = 0.002); B: Kaplan-Meier analysis of overall survival. The median survival in the PDT group was 356 d, vs 230 d in the stent-only group (P = 0.006). ERBD: Endoscopic retrograde biliary drainage.
