Rate of progression at first and third year after diagnosis according to lesion found at entry biopsy
| Rate of progression (95% CI) | |||
|---|---|---|---|
| 12 months | 36 months | ||
| Type III and II IM found at entry biopsy progressed at a higher rate than type I IM or ACG, both at 12 and at 36 months after their diagnosis at baseline or entry biopsy. | |||
| ACG, atrophic chronic gastritis; CI, confidence interval; IM, intestinal metaplasia. | |||
| ACG | 5.4% (2.4% to 8.5%) | 13.5% (7.4% to 19.7%) | |
| Type I IM | 4.1% (1.2% to 7.0%) | 7.4% (3.1% to 11.7%) | |
