Endoscopic and histopathological assessment of individuals undergoing one anastomosis gastric bypass: a 2-year follow-up.
Article in Surgical endoscopy, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
backgroundThere is much debate over the occurrence of biliary reflux to the gastric pouch after one anastomosis gastric bypass (OAGB) and its potential risks.
objectiveTo assess endoscopic and histopathological findings following a standardized protocol of biopsy collection two years after OAGB.
methodsA historical cohort study was conducted, based on a prospectively collected database, which involved 39 participants who underwent OAGB. Participants underwent clinical evaluation and esophagogastroduodenoscopy at the time of surgery and 24 months afterward. Post-operatively, biopsy specimens in esophagogastric junction, pouch, and anastomosis were systematically collected.
results92.3% of the participants were female and the mean age was 37 ± 8.5 years. The mean body mass index (BMI) significantly decreased from 37.6 ± 5.7 kg/m
conclusionsUsing a standardized protocol of post-operative biopsy collection, low rates of severe endoscopic and histopathological abnormalities were observed two years after OAGB. Nevertheless, as most patients have histologically proven inflammation, bile in the gastric pouch, and endoscopic gastritis, long-term surveillance is essential because of the uncertain risk of these abnormalities.
