Weight loss is a major contributor to improved sexual function after bariatric surgery.
Article in Surgical endoscopy, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map.

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.

Abstract
backgroundThe relative contribution of anthropometric, hormonal, and metabolic changes after bariatric surgery (BS) on sexual function (SF) in severely obese subjects is not well established.
methodsProspective observational case series study of 39 men undergoing BS. SF was assessed by means of the international index of erectile function (IIEF) before and at 1 year after surgery. At the same time points, anthropometric (body mass index, waist circumference), hormonal (testosterone, sex hormone binding globulin, estradiol, gonadotropins, inhibin B, prolactin, leptin), and metabolic parameters (insulin sensitivity, C-reactive protein, lipid profile, hemoglobin A1c, presence of hypertension or sleep apnea) were assessed.
resultsBS was associated with marked weight loss (77.18% excess weight loss), improved IIEF score (baseline: 54.85 ± 16.59, 1 year: 61.21 ± 14.10; p < 0.01), gonadal function (testosterone: baseline 256.36 ± 120.98, 1 year: 508.01 ± 161.90; p < 0.001), and improved metabolic profile. However, on multivariate regression analysis whereas changes in body mass index (beta: -0.677, p = 0.001), and baseline IIEF score (beta: -0.397, p = 0.023), were independent predictors of the changes in the IIEF score at 1 year after surgery, changes in hormonal and metabolic factors were not. Variables in the model accounted for 66% of the postsurgical variation in the IIEF score. Similar results were found when the different IIEF-sexual domains were evaluated, except for intercourse satisfaction for which no independent predictor was identified.
conclusionsWeight loss's beneficial effects on SF occurring after BS are beyond the parallel improvement in gonadal and metabolic profiles.
