Early Outcomes and Mid-Term Safety of One Anastomosis Gastric Bypass Are Comparable with Roux-en-Y Gastric Bypass: a Single Center Experience.

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
backgroundThe use of one anastomosis gastric bypass (OAGB) has increased in recent years. However, the efficacy and safety outcomes of this procedure remain under debate. Here, we compare our early outcome and mid-term safety of OAGB with primary Roux-en-Y gastric bypass (RYGB).
methodsThis was a retrospective study using computerized electronic medical records data of patients who underwent RYGB or OAGB as a primary procedure from February 2012 to February 2019 in our bariatric center. Data collected included demographics, weight-outcomes, adverse events, hospital readmission, reoperation rates, and mortality following both procedures.
resultsA total of 314 patients were included (132 RYGB and 182 OAGB). Operative time and costs were significantly lower for OAGB (80 vs. 125 min, p<0.01 and 2018.8 vs. 2912.3 USD, p < 0.01, respectively), but length of hospital stay was longer (4.06 ± 0.67 days vs. 3.58 ± 0.79, p < 0.0001). At 12 months post-surgery, the percentage of excess body mass index loss was comparable between the two groups, but the change in body mass index (BMI) was significantly higher in the OAGB group. Early (< 30 days) and late (> 30 days) surgical adverse events were also similar between the two groups.
conclusionComparable short- and mid-term outcomes and adverse events are found for primary OAGB and RYGB. OAGB is not inferior to RYGB as a primary bariatric procedure for the treatment of obesity.
