	Male				Female
	Daily	Intermediate	Constipated	p value*	Daily	Intermediate	Constipated	p value*
Entire colon Length (cm)	145.8 ± 18.3	151.9 ± 17.1	150.9 ± 17.3	0.26	150.2 ± 16.6	156.3 ± 18.9	160.6 ± 17.7	0.022*

Proximal colon: cecum to descending colon. Distal colon: sigmoid colon and rectum. Bowel habits were classified in a daily group (every day), an intermediate group (once every 2 or 3 days) and a constipated group (less than once in 3 days)
