Comparison of Tissue Eosinophil Counts Between Children with Abdominal Pain-related Functional Gastrointestinal Disorder and Those with Helicobacter pylori Gastritis

	AP-FGID (n = 105)		H. pylori gastritis (n = 27)		P-value
	Mean	95% CI	Mean	95% CI
Antrum	3.9	3.1–4.6	12.7	5.8–19.7	< 0.001
Body	3.7	2.7–4.6	7.7	4.9–10.5	0.002
Duodenum	12.3	10.5–14.1	15.9	11.8–20.0	0.057

AP-FGID, abdominal pain-related functional gastrointestinal disorder; H. pylori, Helicobacter pylori.

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 Mann-Whitney U test.
