What to expect in the excluded stomach mucosa after vertical banded Roux-en-Y gastric bypass for morbid obesity.
Article in Journal of gastrointestinal surgery : official journal of the Society for Surgery of the Alimentary Tract, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 papers, 1 of them a synthesis that pooled it.
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
Mucosal alterations after vertical banded Roux-en-Y gastric bypass have not been clearly evaluated. The aim of this paper was to analyze the histological findings and the presence of Helicobacter pylori in the excluded stomach. Forty consecutive patients who underwent Roux-en-Y gastric bypass longer than 36 months were selected for double-balloon enteroscopy. The excluded stomach was reached in 35/40 patients (88%). Morphological alterations were analyzed through hematoxilin and eosin and the presence of H. pylori was confirmed with Giemsa staining. Thirty patients (86%) were female, and the mean age was 43 years old. The mean postoperative time was 78 months (36-110 months). Histologically, all patients had chronic gastritis in the bypassed stomach, with pangastritis in 33/35 (94%). Five cases (5/35, 14%) presented atrophy and four of them also had intestinal metaplasia. Helicobacter pylori was detected in 7/35 (20%) of the excluded stomach and in 12/35 (34%) of the functional pouch. All patients positive for H. pylori in the excluded stomach were also positive in the functional pouch, p = 0.0005. Helicobacter pylori is still present in the excluded stomach after Roux-en-Y gastric bypass and might be considered for treatment. Histological findings indicated high prevalence of atrophy and intestinal metaplasia in this selected population.
