Conversion to Gastric Bypass After Either Failed Gastric Band or Failed Sleeve Gastrectomy.
Article in Obesity surgery, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 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
backgroundRoux-en-Y gastric bypass (RYGB) is still considered the gold standard in bariatric surgery. Before, adjustable gastric banding (AGB) was regarded as an alternative; nowadays, sleeve gastrectomy (SG) is a more favorable alternative. In case of unsatisfactory results, RYGB is often performed as a secondary procedure. Conversion of an AGB is associated with a high risk of complications; the hypothesis was that this would be less after conversion of an SG.
methodsAll patients undergoing conversion to RYGB after AGB or SG between 2005 and 2012 were included for retrospective analysis. Patient characteristics, operative details, postoperative complications, the relief of complaints, weight loss, reasons for failure, and evolution of known comorbidities up to 2 years were analyzed.
resultsA total of 178 patients were included (79.8 % female): AGB 110 (61.8 %) versus SG 68 (38.2 %). Main reasons for conversion were weight regain/insufficient weight loss (48.4 %) or dysphagia/reflux complaints (39.9 %). Surgical complications were found in 19 patients (AGB 13 vs SG 6; p = 0.530). Infectious complications occurred in 13 patients (AGB 11 vs SG 2; p = 0.135). Total body weight loss was equal between groups after 2 years (AGB 31.6 ± 11.0 % vs SG 31.6 ± 12.0 %; p = 0.998). Similar results were found in a subgroup analysis on patients undergoing conversion for additional weight loss (AGB 31.7 ± 11.7 % vs SG 27.0 ± 13.1 %; p = 0.173).
conclusionsConversion to RYGB after failed AGB or SG showed comparable short-term results in terms of postoperative complications and weight loss.
