*Data were analyzed by chi-square test or Fisher's exact tests. Then, we used logistic regression analyses to estimate the odds ratio (OR) and 95% confidence intervals (CI). The significant results are written in bold; †Continuous variables were summarized as mean±standard deviation (SD) and categorical variables as frequency (%); ‡The tumor size was measured by endoscopist during endoscopy. The A and B group indicate the clear resection margin group and the positive margin group, respectively. ESD, endoscopic submucosal dissection; EMR-L, endoscopic mucosal resection-band ligation.
