Long-term weight change and health outcomes for sleeve gastrectomy (SG) and matched Roux-en-Y gastric bypass (RYGB) participants in the Longitudinal Assessment of Bariatric Surgery (LABS) study.
Observational study in Surgery, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 46 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
backgroundData from a US multicenter longitudinal study of bariatric surgery were used to compare weight change (primary outcome) and comorbidities (secondary outcome) in patients who underwent sleeve gastrectomy versus Roux-en-Y gastric bypass.
methodsThis study includes participants who underwent sleeve gastrectomy and matched participants who underwent Roux-en-Y gastric bypass from the Longitudinal Assessment of Bariatric Surgery-2 (LABS-2) study. Adults undergoing initial bariatric surgical procedures between 2006 and 2009 were enrolled. Participants who underwent sleeve gastrectomy were high-risk or superobese and intended to have a second-stage procedure. Mixed models were used to evaluate percent weight change from baseline through 7 years, and diabetes, dyslipidemia, and hypertension prevalence through 5 years.
resultsFifty-seven of 59 participants who underwent sleeve gastrectomy were matched one to one. Most were female (68%) and white (81%), and had a median age of 49 (37-56) years and median body mass index of 56.4 (35.5-76.8) kg/m
conclusionHigher-risk or super-obese participants after sleeve gastrectomy lost less weight than did matched Roux-en-Y gastric bypass counterparts throughout 7 years. Both groups exhibited improvements in comorbidities from presurgery through 5 years.
