Odds ratio of glandular atrophy (AT) and intestinal metaplasia (IM) in different Helicobacter pylori genotype combinations after adjustment for age
| AT (%) | Non-AT (%) | Odds ratio* (95% CI) | IM (%) | Non-IM (%) | Odds ratio* (95%CI) | |
|---|---|---|---|---|---|---|
| *Common odds ratio was given after adjustment for the effect of age (>50 or ≤50 years) by the Mantel-Haenszel statistics. | ||||||
| 95% CI, 95% confidence interval. | ||||||
| As all strains were of the vacA s1 genotype and 98.1% strains were cagA+, analysis was not possible for these two genotypes. | ||||||
