Giant paraumbilical hernia causing gastric outlet obstruction in a young man with class III obesity: a case report and literature review.
Article in Frontiers in surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Gastric outlet obstruction (GOO) caused by a paraumbilical hernia is exceptionally rare. The stomach is normally tethered by its peritoneal attachments and seldom migrates into a midline ventral defect; reported cases have almost exclusively involved elderly patients, in whom acquired ligamentous laxity has been invoked as a permissive factor. Case description: A 38-year-old man with lifelong class III obesity (peak BMI 48.2 kg/m Conclusion: GOO from a stomach-containing paraumbilical hernia can occur in young patients with severe obesity, where chronically raised intra-abdominal pressure and progressive intra-sac extrusion of viscera through a stable but capacious defect, rather than ligamentous laxity, account for migration of the stomach into the sac. A high index of suspicion, multi-detector CT, formal volumetric loss-of-domain assessment, multidisciplinary optimisation, and retromuscular (Rives-Stoppa) repair offered satisfactory short-term resolution in this patient, with longer follow-up required to confirm durability. The case is reported in accordance with the CARE 2013 reporting guidelines.
