Roux-en-Y Gastric Bypass Versus Sleeve Gastrectomy for Super Super Obese and Super Obese: Systematic Review and Meta-analysis of Weight Results, Comorbidity Resolution.
Synthesis in Obesity surgery, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 25 papers, 4 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) and sleeve gastrectomy (SG) used for super obesity (SO) and super super obesity (SSO) remain controversial. The meta-analysis was to summarize the evidence.
methodsWe searched in MEDLINE and PubMed for studies concerning RYGB and SG for SO or SSO and pooled complication, percentage excess weight loss (%EWL), and resolution of comorbidities.
resultsTwelve studies were identified. RYGB achieved higher %EWL at 12 months, but no significant difference at 24 months. Resolution of diabetes mellitus and dyslipidemia reached a statistical significance; however, there was no significant difference in hypertension.
conclusionsRYGB was superior in %EWL for SSO and SO at 12 months. However, regarding at 24 months, RYGB was equal to SG, which is from a meta-analysis and cannot be seen as a definitive conclusion.
