Data are presented as frequency (%) or median (IQR). P-value is calculated from a Wilcoxon rank-sum test for a numeric variable and a Fisher’s exact test for a categorical variable. *Statistical significance with a P-value less than 0.05. LGIB: lower gastrointestinal bleeding; GI: gastrointestinal; CTA: computed tomography angiography; EGD: esophagogastroduodenoscopy; APC: argon plasma coagulation.
