Prevalence of type 3 intestinal metaplasia (IM) according to biopsy location for all 150 patients
| Oesophagus | GOJ | Corpus | Antrum | |
|---|---|---|---|---|
| Prevalence of type 3 IM (%) | 15/24 (63%)3-160 | 9/18 (50%)† | 0/7 (0%) | 3/15 (20%) |
For each biopsy location, the denominator is the number of patients with intestinal metaplasia at this site. Some patients had intestinal metaplasia at more than one location.
χ2=12.6 (3 df), p<0.01.
