^aP < 0.05: Active inflammation in Helicobacter pylori (H. pylori)-positive patients were compared with -negative patients in the 5-8 years age group.

^bP < 0.05: Active inflammation in H. pylori-positive patients was compared with -negative patients in the 9-12 years age group.

^cP < 0.05: Active inflammation in H. pylori-positive patients was compared with -negative patients in the 13-18 years age group.

^dP < 0.05: Active inflammation was compared between the H. pylori-positive and -negative groups.

Data are n (%), unless otherwise indicated. H. pylori: Helicobacter pylori.
