Crude conditional logistic regression model was inherently adjusted for the matching factors, including study center, sex, age at blood collection (±3 years), date of blood donation (±3 months), time of blood donation (±2 h), and fasting status (<3h, 3–6h or >6 after the last meal).
Adjusted conditional logistic regression model was inherently controlled for the matching factors, and was further adjusted for height, waist-to-hip ratio, smoking status (never, former or current) and diabetes mellitus status (no or yes).
Chronic corpus atrophic gastritis was defined as pepsinogen I <25 µl/l or pepsinogen I/II<3.
