Comparison of the CE findings between the HD and non-HD patients.

	HD patients; (𝑁=19)	Non-HD patients; (𝑁=23)	P value
Abnormal CE findings (highly relevant lesions)	11 (57.9)	15 (65.2)	0.88
Vascular lesions	10 (52.6)	10 (43.5)	0.55
Angioectasia	8 (42.1)	8 (34.8)	0.63
Arteriovenous malformations	0 (0)	1 (4.3)	—
Varices	0 (0)	1 (4.3)	—
Active bleeding with no identifiable cause	2 (10.5)	0 (0)	—
Erosive/ulcerated lesions	5 (26.3)	8 (34.8)	0.83
Ulcerations	2 (10.5)	4 (17.4)	0.89
Erosions (≥3)	3 (15.8)	4 (17.4)	0.93
No findings (less relevant lesions or no abnormalities)	8 (42.1)	8 (34.8)	—

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.
