H pylori infecting groups	AHPDG* Median (range)	AI* Median (range)	AA** Median (range)	BHPDG* Median (range)	BI* Median (range)	BA*, ** Median (range)
Group A	2.00 (0–3)	2.00 (1–6)	2.00 (0–3)	2.00 (0–3)	2.00 (0–5)	1.00 (0–3)

Patients had been subdivided on the basis of H pylori infecting groups A to D. Group A: cagA−, s2, m2, babA2−; group B: cagA+, s1, m1, babA2+; group C: cagA+, s1, m2, babA2+; group D: cagA+, s1, m2, babA2−.

*p<0.05, group A v group B;

**p<0.05, group A v group C; Mann-Whitney test.

AA, antral activity, AHPDG, antral H pylori density grade; AI, antral inflammation; BA, body activity; BHPDG, body H pylori density grade; BI, body inflammation.
