From: Lesion size affects the risk of technical difficulty in gastric endoscopic submucosal dissection
Results of subgroup analysis and interaction analysis between lesion size and the risk of technical difficulty (lesion size per 5 mm increments). All adjusted for age, gender, location (upper, middle, and lower), gross type (elevated, flat, and depressed), surface configuration (erythema, ulcer, and nodularity), submucosal fibrosis (no and yes), and invasion depth (mucosa and non-mucosa). E-value provides an estimate of the required effect size needed for an unmeasured confounder. # P value for the upper third is for the comparison of the middle and lower third. ΔP value for the submucosal fibrosis is for the comparison of non-submucosal fibrosis.
