Patients with irritable bowel syndrome-diarrhea have lower disease-specific quality of life than irritable bowel syndrome-constipation

Table 1 Baseline characteristics of three irritable bowel syndrome-subtypes n (%)

Baseline characteristics	IBS-C	IBS-D	IBS-M	P value
	(n = 54)	(n = 56)	(n = 121)
Age (yr) (mean ± SD)	45.4 (16.0)	42.8 (15.3)	41.3 (14.9)	0.250
Gender
Male	7 (13.0)	5 (9.8)	36 (29.8)	0.0021
Female	47 (87.0)	51 (90.2)	85 (70.2)

¹There was significant difference between gender distribution of irritable bowel syndrome (IBS)-mixed (IBS-M) vs IBS-constipation (IBS-C) (P = 0.02) and IBS-M vs IBS- diarrhea (IBS-D) (P = 0.002).
