Degree of crypt atypia correlates with progression to high-grade dysplasia/adenocarcinoma in non-dysplastic Barrett's oesophagus.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
aimsPatients with non-dysplastic Barrett's oesophagus (BE) often show a wide range of 'atypical' histological features in the bases of the crypts. However, the significance of crypt atypia has never been evaluated, despite prior studies showing the presence of DNA content and other molecular abnormalities in this epithelium. The aim of this study was to evaluate whether the degree of crypt atypia in BE patients without dysplasia correlates with progression to high-grade dysplasia/adenocarcinoma (HGD/EAC). METHODS AND
resultsBaseline biopsies from 114 BE patients without dysplasia, 57 who progressed to HGD/EAC (progressors) and 57 who did not progress (non-progressors), were included in the study. Biopsies were evaluated for the degree of basal crypt atypia on a three-point scale according to discrete histological criteria. In non-progressors, 64.9, 31.6 and 3.5% of biopsies had a crypt atypia score of 1, 2 and 3, respectively, with a mean score of 1.39 ± 0.56. The percentage of biopsies with an atypia score of 2 or 3 increased in progressors [42.1, 42.1 and 15.8% of biopsies scored 1, 2 or 3, respectively, with a mean score of 1.74 ± 0.72 (P = 0.004)]. The odds ratio of grade 3 crypt atypia for progression to HGD/EAC was 5.2 (95% confidence interval = 1.1-25.0, P = 0.04) and the findings did not change significantly when the data were analysed according to progression to either HGD or EAC.
conclusionsThis study shows that non-dysplastic crypts in BE are biologically abnormal, suggesting that neoplastic progression begins prior to the onset of dysplasia. The degree of crypt atypia in BE patients without dysplasia correlates with progression.
