Forest plot analyzing the technique success rate for endoscopic mucosal resection (EMR). (a) the overall technical success rate; (b-d) Subgroup analyses were performed based on the technique used for sessile serrated polyps (SSPs) treatment (cold EMR vs. hot EMR) (b), the size of the SSPs (10–19 mm vs. ≥20 mm) (c), and the method of resection (en-bloc vs. piecemeal) (d)
