Roux-en-Y Gastric Bypass Versus One Anastomosis Gastric Bypass as a Preferred Revisional Bariatric Surgery After a Failed Silastic Ring Vertical Gastroplasty.
Article in Obesity surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 3 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
backgroundOver the years, the silastic ring vertical gastroplasty (SRVG) has shown poor long-term outcomes with both weight regain and complications. Therefore, most bariatric surgeons have been presented with the need to perform a successful and safe conversion procedure. Yet the preferred and recommended conversion surgery regarding weight loss, comorbidity improvement, and postoperative complications remains under debate.
objectiveThe aim of this study is to compare the outcomes of conversion from SRVG with either Roux-en-Y gastric bypass (RYGBP) or one anastomosis gastric bypass (OAGB). MATERIALS AND
methodsA retrospective study was conducted from our bariatric surgery units' database. We reviewed the files of patients who underwent either a RYGBP or OAGB after a previous SRVG. Demographics, obesity-related comorbidities, BMI before and after the procedure, postoperative complications, and length of hospital stay were analyzed.
resultsBetween May 2008 and August 2018, fifty-four patients underwent conversion from a failed SRVG. Twenty-one patients underwent conversion to OAGB (39%), and thirty-three patients underwent conversion to RYGBP (61%). Major complications were reported in 9.5% of the OAGB group and 15.1% of the RYGBP group. At a mean follow-up of 28 months, the OAGB group achieved a 78.5% excess BMI loss compared with 57.6% in the RYGBP group (p = 0.137). One patient (4.7%) of the OGBP group and 5 (15.1%) of the RYGBP group needed reoperations due to complications (p = 0.224).
conclusionThe OGBP is gaining popularity and evidence as an effective and safe procedure. Here we show the successful utilization of the OGBP, when compared with RYGBP, as a revisional procedure after SRVG.
