Small bowel lesions that were considered to be the cause of the OGIB, such as angioectasia, dieulafoy's lesions, varices, arteriovenous malformations, ulcerations, multiple (≥3) erosions, diverticula, or the presence of blood and/or blood clots in the lumen of the small bowel, were considered as highly relevant lesions. P values were calculated using the chi-squared test.
