The United States Experience with One Anastomosis Gastric Bypass at MBSAQIP-Accredited Centers.
Observational study in Obesity surgery, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
purposeOne anastomosis gastric bypass (OAGB) has emerged as a potentially safe and effective weight-loss procedure. Worldwide, OAGB is the third most commonly performed primary bariatric procedure, comprising 4% of the annual volume. In the USA, OAGB has yet to be endorsed as a primary bariatric procedure and can only be performed under research protocols or as a revision procedure. MATERIALS AND
methodsWe performed an observational cohort study to describe the preoperative, intraoperative, and postoperative characteristics of adult patients who underwent primary or revision OAGB from 2015 to 2019 at MBSAQIP centers. Exclusion criteria included emergent surgery, incomplete 30-day follow-up, and non-laparoscopic- or robotic approach.
resultsDuring the study period, 803,906 bariatric procedures were performed and 645 (0.08%) were OAGB. Among these, 436 (67.6%) were primary and 209 (32.4%) were revision OAGB. The mean operation time was 89 min (SD, 59) and 8% were performed using a robotic approach. The overall complication rate was 7.4% and there was one death (0.2%). The post-operative complication rates were generally higher than the early complication rate (3.4%) reported in the YOMEGA trial, an RCT from France. Revision OAGB had a longer mean operation time of 141 min (SD, 85, p < 0.001).
conclusionPrimary OAGB was a rarely performed bariatric procedure at MBSAQIP-accredited centers comprising only 0.05% compared to 4% worldwide. Future studies should compare safety of OAGB to that of established bariatric procedures like Roux-en-Y gastric bypass and sleeve gastrectomy.
