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
BACKGROUND &
aimsEndoscopic eradication therapy (EET) for Barrett's esophagus (BE) has unclear effects on the gastric cardia. We investigated the prevalence of intestinal metaplasia (IM) and dysplasia in the cardia after complete eradication of IM (CEIM) and the incidence of newly diagnosed cardia IM or dysplasia after EET.
methodsWe performed a prospective study, from 2013 through 2016, of patients with previously successful EET undergoing surveillance after CEIM (cross-sectional group) and treatment-naïve patients with BE undergoing EET (longitudinal group). Standard biopsies were collected from multiple levels in the cardia and analyzed histologically. We calculated the prevalence (cross-sectional group) and the incidence (longitudinal group) of cardia IM or dysplasia after EET.
resultsOf the 116 patients in the cross-sectional group, 17 (15%) had cardia IM or dysplasia after CEIM: 12 patients had IM, 2 patients were indefinite for dysplasia, and 3 patients had low-grade dysplasia. Cardia IM or dysplasia were most commonly found at the tops of gastric folds. Among 42 subjects in the longitudinal group, the pre-treatment prevalence of cardia IM or dysplasia was 28.5% (3 with non-dysplastic IM, 9 with dysplastic IM, 1 indefinite for dysplasia, 2 with low-grade dysplasia, 3 with high-grade dysplasia, and 3 with intramucosal cancer). All achieved CEIM. The incidence of cardia IM or dysplasia was 11.9% after 18 months of follow up. IM or dysplasia was more higher in the cardia after CEIM than in the tubular esophagus (P < .01).
conclusionsIn a prospective study, we found that cardia dysplasia becomes less, not more, common, after successful EET; recurrence of IM or dysplasia was more frequent in the cardia than the esophagus. Patients with BE undergoing EET should have careful examination of the cardia, with a single set of surveillance biopsies at the top of the gastric folds.
