One Anastomosis Gastric Bypass after Sleeve Gastrectomy Failure: Does a Single Procedure Fit for all?

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
introductionConsidering the multitude of bariatric procedures performed all over the world, the necessity of revisional surgery increased accordingly. Several authors argued that with the great diffusion of sleeve gastrectomy (SG), the number of patients who experienced a weight regain at long follow-up was congruous and physiologic, even if not negligible. Recent studies showed that one anastomosis gastric bypass (OAGB) was an effective and safe option also as redo surgery. The aim of the study was to evaluate effectiveness of OAGB as redo surgery after SG in term of anthropometric features and remission of comorbidities.
methodsBariatric patients experiencing weight regain and insufficient weight loss after SG and undergoing OAGB as redo surgery were retrospectively analyzed. During post-OAGB outpatient visit weight, %EWL, BMI, comorbidities, and vitamin deficiencies were evaluated. A further visit was scheduled for the evaluation of postoperative esophagitis/gastritis at upper endoscopy.
resultsFifty-nine (Reviewer #3-1) patients underwent OAGB as redo-surgery consequently to the worsening of the bariatric outcomes at 29.42 ± 7.29 months from SG (mean weight, BMI and %EWL were 120.89 ± 16.79 kg, 43 ± 4.39 and 19.84 ± 30.29, respectively). Conversely, at a mean follow-up of 34.32 ± 1.71 months (Reviewer #3-3) after OAGB, no weight regain or insufficient weight loss cases were recorded (mean weight 71.25 ± 10.22 kg, mean BMI 24.46 ± 2.06 kg/m2, mean %EWL 69.49 ± 14.4, p < 0.0001) (Reviewer #3-2).
conclusionOAGB is a safe and effective bariatric procedure in terms of morbidity, mortality, and %EWL also as revision surgery after SG. Further larger studies are needed to address this issue.
