Roux-en-O after revisional bariatric surgery: a rare complication following OAGB to RYGB conversion.
Article in Journal of surgical case reports, 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
Roux-en-O (ROGB) configuration is a rare technical complication caused by incorrect limb orientation, resulting in biliopancreatic secretions draining into the gastric pouch. We report a 47-year-old female with multiple prior bariatric surgeries who underwent conversion to Roux-en-Y gastric bypass for refractory gastroesophageal reflux disease and developed persistent food intolerance, bilious vomiting, and reflux. ROGB was suspected on imaging and confirmed intraoperatively. Surgical revision with reconstruction of the gastrojejunostomy and jejunojejunostomy restored proper limb orientation, leading to complete symptom resolution. This case emphasizes the importance of careful limb identification during revisional bariatric surgery to prevent this rare complication.
