Design outcomes

Primary

Measure	Time frame
The differences in the ratio of complete intestinal metaplasia and incomplete intestinal metaplasia according to micro-mucosal pattern (foveola type, groove type).	—

Secondary

Measure	Time frame
1. The difference in the ratio of micro-mucosal pattern (foveola type, groove type) according to the localization of intestinal metaplasia. 2. The difference in the macroscopic type in white light imaging according to micro-mucosal pattern (foveola type, groove type). 3. The difference in color in white light imaging according to micro-mucosal pattern (foveola type, groove type). 4. The frequency of LBC by micro-mucosal pattern (foveola type, groove type). 5. The frequency of WOS by micro-mucosal pattern (foveola type, groove type). 6. The difference in the frequency of gastric epithelial tumors (including a history) with and without endoscopic intestinal metaplasia. 7. The Relationship between micro-mucosal pattern (foveola type, groove type) and H. pylori infection status (currently infected or already infected). 8. The difference in the extent of atrophic gastritis by micro-mucosal pattern (foveola type, groove type). 9. Intra-observer concordance rate and inter-observer concordance rate of micro-mucosal pattern (foveola type, groove type). 10. The differences in the ratio of complete intestinal metaplasia and incomplete intestinal metaplasia according to markers of intestinal metaplasia (LBC, WOS, MTB).	—
