Antral biopsies were examined \u201cblind\u201d to clinical group and graded for a series of histological features from which the \u201creflux gastritis score\u201d (RGS) and \u201cbile reflux index\u201d (BRI) could be calculated.

The RGSs did not differ between groups. BRI values in the Barrett's group were significantly higher than those in GORD subjects (p=0.014) which in turn were higher than those in NUD patients (p=0.037). Similarly, the frequency of high BRI values (&gt;14) was significantly greater in the Barrett's group (29\/100; 29%) than in the GORD (9\/61; 14.8%) or NUD (4\/50; 8%) group.
