Gender influence on long-term weight loss after three bariatric procedures: gastric banding is less effective in males in a retrospective analysis.
Article in Surgical endoscopy, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 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
backgroundIdentifying factors that influence weight loss after bariatric surgery is one way to predict a successful surgical outcome. Knowledge of the effect of gender on weight loss after bariatric surgery has not been well demonstrated in the literature despite being noted in every day practice. The aim of this study was to find the influence of gender on long-term weight loss after bariatric surgery.
methodsA retrospective analysis of data retrieved from a prospectively maintained bariatric database was conducted.
resultsThe study included 640 consecutive patients. Their mean age was 38 ± 10 years, mean preoperative body mass index was 44.9 ± 8.4 kg/m2, and mean preoperative excess weight (EW %) was 108.3 ± 38.4%. The mean of the average excess weight loss (EWL %) was 43.3 ± 42.4%. Three procedures were utilized: Roux-en-Y gastric bypass (RYGB), vertical banded gastroplasty (VBG), and gastric banding (GB). Both VBG and RYGB induced significantly more EWL % than GB (d = 22.1%, p < 0.001 and d = 16, p = 0.02, respectively). In patients who underwent VBG and GB, males had significantly lower preoperative EW % (Student t = -4.86, p < 0.001, and Student t = 4.69, p < 0.001, respectively), and postoperative mean of the average EWL % (Student t = -2.43, p = 0.016, and Student t = -3.33, p = 0.002, respectively) than females. In patients who underwent RYGB, there were no differences in the preoperative EW % (t = -1.03, p = 0.309) or the mean of the average EWL % (t = 0.406, p = 0.688). The simple linear regression model used to explain the variability in EWL %, accounted for by the variability in the preoperative EW %, was significant (F = 180, p < 0.001). Analysis of the residual errors in predicting the EWL % revealed no significant difference between males and females after VBG and after RYGB (t = 0.117, p = 0.907 and t = 1.052, p = 0.3, respectively), while it was significant after GB (t = -2.999, p = 0.003).
conclusionFrom our experience, we suggest that GB not to be offered as a first choice for obese male patients.
