The bariatric surgery and weight losing: a meta-analysis in the long- and very long-term effects of laparoscopic adjustable gastric banding, laparoscopic Roux-en-Y gastric bypass and laparoscopic sleeve gastrectomy on weight loss in adults.

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
backgroundSeveral studies have been investigated to find the long-term effect of bariatric surgery on weight loss; nevertheless, a meta-analysis can detailedly demonstrate the effect of bariatric surgery on weight in morbidly obese patients. This study aimed to assess the long- and very long-term effects of laparoscopic adjustable gastric banding (LAGB), laparoscopic Roux-en-Y gastric bypass (LRYGB), and laparoscopic sleeve gastrectomy (LSG) on weight loss in adults.
methodsAn electronic search using PubMed, Scopus, and Google scholar databases was performed for all English-language articles up to May 15, 2016 with no publication date restriction. Outcome was long-term (≥5-10 years) and very long-term (≥10 years) weight reduction that reported as the mean %EWL and changes in BMI from baseline.
resultsEighty articles with 87 arms were included in this meta-analysis. The excess weight loss percentage (%EWL) was 47.94% and 47.43% after LAGB at ≥5 and ≥10 years, respectively. After LRYGB the %EWL was 62.58% at ≥5 years and 63.52% at ≥10 years. It was 53.25% at ≥5 years after LSG. Results of subgroup analyses have indicated that LRYGB leads to higher %EWL in America and Asia compared with Europe. Meta-regression analyses have shown that there is no significant association between %EWL and baseline age, BMI and length of follow-up after three procedures. However, there is a positive association between gender and %EWL after LRYGB (β = 1.24). No publication bias was found.
conclusionsThese findings suggest that LRYGB is an effective procedure in morbidly obese patients that leads to sustainable weight loss over the long- and very long-term periods in compared with LAGB and LSG.
