One-anastomosis gastric bypass reversal due to severe malnutrition and acute hepatic failure: a case report.
Article in Journal of surgical case reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The one-anastomosis gastric bypass (OAGB) is one of the most popular performed bariatric surgeries and has good long-term success for treating obesity and metabolic diseases. However, some patients can develop severe complications such as malnutrition and hepatic steatosis, which can be corrected with a reversal procedure, as seen in this case. A 20-year-old woman underwent OAGB surgery, which was converted to Roux-en-Y gastric bypass 4 months after the initial procedure due to malnutrition, both surgeries were performed at a hospital in southern Mexico. After the second surgery, she presented to our hospital with intolerance to oral feeding, vomiting and loss of 44 kg in 4 months. The patient was stabilized and scheduled for reversion surgery to normal anatomy 5 months later. She had good short-term nutritional outcomes and at the 1-year follow-up her total weight gain was 14 kg.
