By site prevalence of atrophic gastritis (distinguishing between atrophy with and without IM) in 504 consecutive Helicobacter pylori positive patients. Patients with phenotype “indefinite for atrophy” and/or “foveolar restricted IM” were included among cases of non-atrophic gastritis

IM, intestinal metaplasia.

Incisura angularis, number of patients whose gastric atrophy (with or without IM) was detected only in the incisura biopsy samples.

Antrum, number of patients whose gastric atrophy (with or without IM) was detected only in the antral biopsy samples.

Antrum and incisura angularis, number of patients whose gastric atrophy (with or without IM) was detected in both the antral and the incisura angularis biopsy samples.

Corpus, number of patients whose gastric atrophy (with IM) was detected only in the corpus biopsy samples.
