The prevalences of oesophagogastric junctional complete and incomplete intestinal metaplasia (IM) in different types of gastritis
| Junctional complete IM (n=134) | Junctional incomplete IM (n=101) | |
|---|---|---|
| Normal gastric histology (n=417)2-151 | 24 (18; 11 to 24) | 29 (29; 20 to 38)* |
| Antral predominant non-atrophic gastritis (n=421, 78% H pylori positive2-152) | 60 (45; 36 to 53) | 40 (40; 30 to 49) |
| Antral predominant atrophic gastritis (n=86, 81%H pylori positive) | 18 (13; 8 to 19) | 20 (20; 12 to 28) |
| Corpus predominant atrophic gastritis (n=75, 26%H pylori positive) | 17 (13; 7 to 18) | 10 (10; 5 to 17) |
| Multifocal atrophic gastritis (n=360, 57%H pylori positive) | 15 (11; 6 to 17)** | 2 (2; 0 to 7) |
| Chronic gastritis, all types (n=618, 71% H pylori positive) | 110 (82; 76 to 89)* | 72 (71; 63 to 80) |
Values in parentheses are percentage with 95 confidence interval of the total amount of the IM subtype.
Within each type of gastritis, the prevalences of IM subtypes were compared with each other using the rest of study population with junctional IM as reference group (χ2 test).
