Roux-en-Y gastric bypass versus one anastomosis-mini gastric bypass as a rescue procedure following failed restrictive bariatric surgery. A systematic review of literature with metanalysis.

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
backgroundAlthough different procedures have been proposed as revisional surgery for patients who had previously undergone a failed primary restrictive procedure, the ideal revisional procedure is still a matter of debate.
methodsA systematic search was performed in all electronic databases to find studies comparing one anastomosis-mini gastric bypass (OAGB-MGB) or Roux-en-Y gastric bypass (RYGB) as revisional bariatric surgery for weight regain or intolerance/complications of a primary restrictive procedure. The data regarding sample size, patients' gender, age, primary surgery type, number of perioperative complications, operative time, pre- and post-revisional body mass index (BMI), and excess weight loss % (EWL%) at 1-year follow-up were extracted. Five studies were included in the analysis.
resultsThe primary bariatric procedures were represented by vertical banded gastroplasty (VBG), laparoscopic adjustable gastric band (LAGB) and laparoscopic sleeve gastrectomy (LSG). About perioperative complications, both RYGB and OAGB-MGB showed a similar rate of leaks but OAGB-MGB had a lower rate of bleedings; considering the progression from pre- to post-revisional BMI, OAGB-MGB reveals a better outcome as well as a shorter operative time.
conclusionsOur meta-analysis has shown OAGB-MGB, used as revisional intervention after failed restrictive surgery, achieves outcomes comparable to RYGB in terms of perioperative complications providing a simpler and more effective technique.
