a

P < 0.05 when type I Helicobacter pylori (H. pylori)-infected groups were compared with H. pylori-negative groups.

b

P < 0.05 when type II H. pylori-infected groups were compared with H. pylori-negative groups.

c

P < 0.05 when type I H. pylori-infected groups were compared with type II H. pylori-infected groups.

d

P < 0.05 when H. pylori-infected groups were compared with H. pylori-negative groups.

Data are presented as mean ± SD. G-17: Gastrin-17; PG: Pepsinogen; PGR: PG I/II ratio; Type I H. pylori: H. pylori infection with type I strains; Type II H. pylori: H. pylori infection with type II strains; H. pylori: Helicobacter pylori; H. pylori+: H. pylori-positive; H. pylori-: H. pylori-negative.
