NAG, non-atrophic gastritis; MAG, multifocal atrophic gastritis without intestinal metaplasia; IM, intestinal metaplasia.

Dysplasia includes indefinite for dysplasia, low-grade, and high-grade. Gray cells denote the numbers of individuals who had the same histological diagnosis at baseline and at 20 years of follow-up. On the left side of the diagonal are individuals who regressed; on the right, those who progressed.

With the exception of GC, all histological diagnoses from endoscopies at intermediate time points were excluded from this table.
