Complete clip closure with staged triple-lumen feeding tube reduces delayed adverse events after duodenal endoscopic submucosal dissection

Figure 2 Subgroup χ² analyses of the association between titanium clip closure quality and postoperative complications after duodenal endoscopic submucosal dissection. The patients were stratified by age, gender, body mass index, comorbidity, lesion location, drainage strategy, and year of admission. The χ² test was used within each subgroup to compare the incidence of complications between the two groups. BMI: Body mass index.
