Abstract

The purpose of this letter was to explore how lesion size affects the pooled effect of traction-assisted endoscopic submucosal dissection on procedure time. Our meta-regression showed that lesion size negatively associated with the effect of traction-assisted endoscopic submucosal dissection on procedure time (estimate point = − 1.02; 95% confidence interval, from − 1.58 to − 0.46). We also confirmed this result in different statistical models including fixed effect regression and two mixed effects regression models.
