Table 1 Demographic variables for IBS patients and controls

	D-IBS (n = 42)	C-IBS (n = 24)	Controls (n = 52)
Age (mean ± SD)	27.0 ± 6.4	32.5 ± 8.8	27.3 ± 8.0
Sex (female), n (%)	29 (69)	16 (67)	34 (64)
FBDSI	62.8 (23.2)	68.4 (25.3)	2.1 (4.9)
Self-reported race/ethnicity n (%)

D-IBS: Diarrhea-predominant irritable bowel syndrome; C-IBS: Constipation-predominant irritable bowel syndrome. Columns may not sum to 100%, because values were rounded to the nearest 1%. Scores on the Functional Bowel Disorder Severity Index (FBDSI) that share a superscript are different at P < 0.01.
