Correlation between increased ultrasonographic bowel-wall thickness and colonoscopic activity in different segments of the colon.

Segment of the colon	Patients with BWT ≥3 mm	Patients with SES-CD ≥3	r s-value	P-value
Ileum	83 (70.9)	60 (51.3)	0.483	<0.001
Right colon	54 (46.2)	53 (45.3)	0.576	<0.001
Transverse	33 (28.2)	31 (26.5)	0.660	<0.001
Left colon	35 (29.9)	33 (28.2)	0.609	<0.001
Rectum	7 (6.0)	12 (10.3)	0.332	<0.001

Data are presented as n (%).

BWT, bowel-wall thickness; r_s, Spearman’s rank correlation coefficient; SES-CD, simple endoscopic score for Crohn's disease.
