Figure 2 Kaplan-Meier survival curve of randomized patients treated with PDT plus stenting (group A, n = 20) and of patients with stenting alone (group B, n = 19). Survival was longer in group A compared with group B (P < 0.0001). +, Patients still alive. Gastroenterology 2003 125, 1355-1363DOI: (10.1016/j.gastro.2003.07.015)

Figure 3 Mean serum bilirubin levels in randomized patients treated with PDT plus stenting (group A, n = 20) and of patients with stenting alone (group B, n = 19). In groups A and B, bilirubin levels remained elevated after stenting. Post-PDT bilirubin levels decreased in group A (P < 0.01). The error bars are the SEM.
