Figure 4From: A comparison of the temporary placement of 3 different self-expanding stents for the treatment of refractory benign esophageal strictures: a prospective multicentre study Clustered multiple variables graph with mean dysphagia scores over time after temporary placement of self-expandable plastic stent (SEPS), biodegradable (BD) stent and fully cover self-expandable metal stent (SEMS). Bars represent 95% CI for mean. Dysphagia score improved significantly from baseline level to 4 weeks after stent placement (p < 0.001) in the 3 groups. Dysphagia score improved significantly from baseline level to post treatment for BD stent and fully cover SEMS but not for SEPS. (final post-treatment after stent removal and dysphagia recurrence for all patients).Back to article page
