Fig 1 The dysphagia grades significantly improved in both groups within the first month after stent placement (p < 0.01) and worsened at 3 months, but it was better in the irradiation stent group than in the traditional stent group (p = 0 .03).

Fig 2 The median survival was 4.0 months (95% confidence interval [CI], 3.5 to 4.5 months) in the irradiation stent group and 3.0 months (95% CI, 2.4 to 3.6 months) in the traditional stent group, respectively. The survival differences between the 2 groups were not significant (p = 0.064). (cum = cumulative.)
