Comparison of Gastric and Duodenal Eosinophil Counts Between Children with Abdominal Pain-related Functional Gastrointestinal Disorders and Normal Controls

	AP-FGID (n = 105)		Normal control (n = 19)		P-value
	Mean	95% CI	Mean	95% CI
Antrum	3.9	3.1–4.6	1.9	1.3–2.5	< 0.001
Body	3.7	2.7–4.6	2.1	0.8–3.4	0.045
Duodenum	12.3	10.5–14.1	9.6	6.5–12.7	0.127

AP-FGID, abdominal pain-related functional gastrointestinal disorder.

The mean number and 95% CI of eosinophils/high-power field for each anatomical region of the upper gastrointestinal tract.

P-value was calculated by independent t test.
