One Anastomosis Gastric Bypass as a Revisional Procedure After Failed Laparoscopic Adjustable Gastric Banding.
Article in Obesity surgery, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 2 of them syntheses 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
backgroundRecent data demonstrates that laparoscopic adjustable gastric banding (LAGB) is found to be associated with high rates of weight loss failure and long-term complications. Therefore, the search for the optimal revisional bariatric procedure is ongoing.
objectiveWe aim to assess the safety and efficacy of converting a failed LAGB to laparoscopic one anastomosis gastric bypass (OAGB) as a revisional procedure.
settingLarge, metropolitan, tertiary, university hospital.
methodsRetrospective review of patients who underwent OAGB after LAGB.Demographics, comorbidities, BMI before and after the procedure, complications, and length of stay were documented.
resultsFifty-seven patients underwent OAGB after LAGB. For 41 patients, the band was removed, and an OAGB was performed in a single procedure (71.9%), and 96.5% of the cases were completed laparoscopically. Postoperative complications occurred in 9 patients (15.7%), including one mortality. Average BMI decreased from 42.8 ± 7.0 to 31.3 ± 5.2 kg/m
conclusionsConversion of a failed LAGB to OAGB is effective but carries higher complication rates. Randomized controlled studies comparing different procedures are necessary to further clarify the optimal revisional bariatric operation.
