Weight Loss Failure and Reoperation After Laparoscopic Adjustable Gastric Banding and Gastric Bypass: a Case-Matched Cohort Study.
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 3 papers.
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
introductionNot long ago, laparoscopic adjustable gastric banding (LAGB) was considered a safe and effective treatment of morbid obesity; however, long-term outcomes revealed significant complication and failure rates. We hypothesized that LAGB has higher rates of weight loss failure, reoperation, and overall failure compared to laparoscopic gastric bypass (LRYGB) at long-term follow-up.
methodsA matched case-control study was performed. Patients who underwent primary LAGB or LRYGB at a university hospital between 2004 and 2011 were propensity matched for age, gender, race, body mass index (BMI), and weight-related co-morbidities. Outcomes included demographics, percent excess weight loss (% EWL) and reoperation, weight loss failure (<50% EWL), and overall failure (procedure-related reoperation and/or <50% EWL) at 3- and 5-year follow-up.
resultsIn all, 228 LAGB and 228 LRYGB patients matched. LAGB patients had less mean EWL at 3 years (35 vs. 71%, P < 0.05) and 5 years (29.3 vs. 66.7%, P < 0.05). LAGB (11%) and LRYGB (11.5%) patients required procedure-related reoperation. More LAGB patients suffered weight loss failure at 3 years (75 vs. 10.5%, P < 0.05) and 5 years (81.5 vs. 15.4%, P < 0.05). Overall failure rates were higher after LAGB. The most common complication after LAGB was pouch/esophageal enlargement (9.7%) and after LRYGB was internal hernia (4.8%). LAGB patients had higher morbidity (19 vs. 12.7%, P = 0.04) but similar procedure-related mortality (0 vs. 0.4%).
conclusionsLAGB has significantly higher rates of weight loss failure compared to LRYGB with similar rates of procedure-related reoperation. Overall failure rates are higher after LAGB. These data suggest the long-term effectiveness of LAGB might be limited.
