Intralesional steroid is beneficial in benign refractory esophageal strictures: A meta-analysis

Figure 1 Prisma flow chart of the study selection process.

Figure 2 Forest plot of the random effect analysis of the 4 studies concerning periodic dilation index shows a significant decrease of periodic dilation index after intralesional steroid injection in addition to endoscopic dilation.

Figure 3 Forest plot of the random effect analysis of the 5 studies concerning total number of repeat dilation shows a non-significant decrease of total number of repeat dilation after intralesional steroid injection in addition to endoscopic dilation.

Figure 4 Forest plot of the random effect analysis of the 5 studies concerning dysphagia score shows no significant improvement of dysphagia score after intralesional steroid injection in addition to endoscopic dilation.
