Serum biomarkers and clinical disease activity indices in inflammatory bowel disease patients with anemia compared to those without anemia.

	IBD patients with anemia	IBD patients without anemia	P value
Median CRP (mg/L, IQR)	0.5 (0.2-1.7)	0.2 (0.1-0.6)	<0.0001
Median ESR (1^st h, IQR)	12 (7-21)	8 (5-15)	<0.0001
Median HBI (for CD, IQR)	4 (2-8)	3 (1-6)	<0.0001
Median UCAI (for UC, IQR)	4 (1-10)	2 (0-5)	<0.0001

CD, Crohn’s disease; UC, ulcerative colitis; IBD, inflammatory bowel disease; CRP, C-reactive protein; IQR: interquartile range; ESR, erythrocyte sedimentation rate; HBI, Harvey-Bradshaw index; UCAI, ulcerative colitis activity index
