Autonomic functions and gastric motility in children with functional abdominal pain disorders

Table 3 Comparison of gastric motility parameters between children with abdominal pain-predominant functional gastrointestinal disorders and controls

Gastric motility parameter	AP-FGIDs, n = 100	Controls, n = 50	P value1
	Median (range)	Median (range)
Fasting antral area, cm2	1.6 (0.4-5.9)	1.3 (0.4-5.1)	0.19
Antral area at 1 min, cm2	9.8 (3.8-14.6)	9.8 (3.4-19.1)	0.42
Antral area at 15 min, cm2	4.8 (0.9-10.7)	3.6 (0.6-11.2)	< 0.0001
Gastric emptying rate, %	46.3 (16.0-77.9)	61.6 (10.0-88.5)	< 0.0001
Frequency of antral contraction, /3 min	8.0 (6-11)	9.0 (8-11)	< 0.0001
Amplitude of antral contraction, %	47.2 (22.8-83.0)	59.4 (32.6-85.4)	< 0.0001
Antral motility index	4.0 (1.7-7.5)	5.7 (2.9-8.1)	< 0.0001
