Delayed orocecal transit in pediatric gut-brain interaction disorders: A comparative study using the lactulose breath test

Table 1 Comparison of orocecal transit times between patients with functional abdominal pain disorders and controls

Group	Mean (minutes)	Median	IQR	SD	P value1
FAPDs (n = 34)	93.3	90	75-120	30.6	0.0045
Controls (n = 19)	68.4	75	60-75	17.0

¹Mann-Whitney U-test.

FAPD: Functional abdominal pain disorders; IQR: Interquartile range.
