Caecal pH is a biomarker of excessive colonic fermentation

Table 1 A comparison of the regional transit times between patients and healthy controls

Transit time(min)	Patients(mean ± SD)	Controls(mean ± SD)	P value
GET	290 ± 76	306 ± 55.9	0.86
SBTT	305 ± 14.5	270 ± 25.9	0.24
CTT	1443 ± 192.8	1861 ± 263.7	0.21
WGTT	2039 ± 202	2437 ± 279.4	0.26

GET: Gastric emptying time; SBTT: Small bowel transit time; CTT: Colonic transit time; WGTT: Whole gut transit time.
