Table 2. Gastric, small intestinal, and colonic transit.

Unless stated otherwise, all values are Mean ± SD

	Rapid GE1 only (n=102)	Rapid GE2 only (n=36)	Rapid GE1 and GE2 (n=73)	Normal GE1 and GE2 (n=2075)
Gastric emptying at 1 hour	40 ± 8	29 ± 6	48 ± 14	19 ±7
Gastric emptying at 2 hours	67 ± 10	82 ± 6	85 ± 7	47±13
Gastric emptying at 4 hours	94 ± 7	98 ± 3	98 ± 2	86 ± 11
Small bowel transit (CF6)
n (%)	99 (97%)	35 (97%)	71 (97%)	2062 (99%)
Value	45 ± 32	47 ± 29	51 ± 32	46 ± 29
Geometric center at 24 hours (GC24)
n (%)	79 (78%)	27 (75%)	61 (84%)	1692 (82%)
Value	2.4 ± 1.1	2.1 ± 0.7	2.4 ± 1.1	2.1 ± 11
Delayed GC24 (<1.6), n (%)	13 (13%)	3 (7%)	5 (7%)	406 (20%)*
Accelerated GC24 (>3.8), n (%)	12 (12%)	1 (1%)	9 (12%)	174 (8%)

CF6 = colonic filling at hours; GC24 = geometric center for colonic transit at 24 hours
