Mini/One Anastomosis Gastric Bypass Versus Roux-en-Y Gastric Bypass as a Second Step Procedure After Sleeve Gastrectomy-a Retrospective Cohort Study.
Article in Obesity surgery, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05608772 (Conversion of Failed Sleeve Gastrectomy Due to Weight Regain to SADI-S, RYGB or OAGB), which is not on this map.

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.

Abstract
backgroundWhether one anastomosis gastric bypass (OAGB) or Roux-en-Y gastric bypass (RYGB) is a better revisional bariatric surgery (RBS) after sleeve gastrectomy (SG) is still under debate. The aim is to compare short-term outcomes of RYGB and OAGB as a RBS after SG, pertaining to their effects on weight loss, resolution of comorbidities, and complications.
methodsWe performed a single-center analysis of 55 patients (n = 34 OAGB, n = 21 RYGB). Indications for revisional surgery included weight regain/loss failure (67%) and intractable gastroesophageal reflux disease (33%). Data were collected up to 1-year follow-up (FU) and included time of revisional surgery, operation time, weight, body mass index, excess weight loss, and total weight loss (TWL), both in percent, complications and resolution of comorbidities.
resultsOperation time was 79 ± 36 (OAGB-MGB) and 98 ± 24 min (RYGB) (p = 0.03). In the first 30 postoperative days, three patients in the RYGB group, and no patient in the OAGB group, had postoperative complications. FU was 100%. Minor complication rates at 12 months were 33.3% (RYGB) and 35.3% (OAGB). At 12 months, mean % TWL was 10.3 ± 7.6% (RYGB) and 15.8 ± 7.8% (OAGB) (p = 0.0132).
conclusionsOAGB after failed SG was found to be a quicker procedure with less perioperative complications. At 1-year FU, no significant differences were seen between RYGB and OAGB regarding readmission and minor complications. Still long-term FU including the risk of malnutrition is needed to have a complete evaluation of OAGB as a RBS for the future.
