Conversion of One-Anastomosis Gastric Bypass (OAGB) to Roux-en-Y Gastric Bypass (RYGB) is Effective in Dealing with Late Complications of OAGB: Experience from a Tertiary Bariatric Center and Literature Review.
Article in Journal of metabolic and bariatric surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Purpose: Both primary and revisional bariatric surgery are on the rise due to global obesity pandemic. This study aimed to assess the indications for revision after one-anastomosis gastric bypass (OAGB) and the outcomes after laparoscopic conversion of OAGB to roux-en-y gastric bypass (RYGB). Materials and Methods: Retrospective review on patients that had undergone conversion of OAGB to RYGB between June 2007-June 2019 in a tertiary bariatric center, followed by literature review. Results: Out of 386 revisional bariatric surgery, a total of 14 patients underwent laparoscopic conversion of OAGB to RYGB. The mean age was 44.7 with 71% female. The mean pre-revision BMI was 29.2 kg/m Conclusion: Bile reflux, marginal ulcer, IWL/WR and malnutrition were the main indications for revision after OAGB in this study. In concordance with the available evidence, laparoscopic conversion of OAGB to RYGB was safe and effective in dealing with late complications of OAGB.
