1 · What the graph read from 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.

2 · The registry

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

introductionObesity is a worldwide public health issue with serious psychological and social impacts. Erectile dysfunction is also a common clinical condition, and obesity is one of its main risk factors.

objectiveThe objective of this study was to systematically evaluate the effect of bariatric surgery on male sexual function.

methodsA systematical research was carried out in Medline via PubMed, EMBASE, Cochrane Library, and Web of Science up to March 16, 2019, to identify published articles related to bariatric surgery and male sexual function in men. Two reviewers screened literature, extracted data, and assessed the quality of included studies. I

resultsA total of 12 studies involving 420 participants were included. Analysis showed that bariatric surgery significantly reduced body mass index in morbidly obese patients (mean difference [MD] = -13.73; 95% CI -17.23 to -10.22; P < .00001). From 10 studies that reported the International Index of Erectile Function (IIEF) score, bariatric surgery led to a significant increase in IIEF-total score (MD = 8.2; 95% CI = 5.52-10.88; P < .00001), and erectile function score (MD = 3.76; 95% CI = 2.34-5.19; P < .00001), sexual desire (MD = 0.93; 95% CI = 0.55-1.32; P < .00001), sexual intercourse satisfaction (MD = 1.73; 95% CI = 0.43-3.03; P < .01), and total satisfaction (MD = 1.28; 95% CI = 0.56-2.00; P = .0005) were also significantly improved. However, bariatric surgery did not affect orgasm function (MD = 0.26; 95% CI = -0.15 to 0.68; P = .21). Three studies that reported the IIEF-5 score also showed a significant improvement of erectile function (MD = 5.45; 95% CI = 3.38-7.52; P < .00001).

conclusionsBariatric surgery could improve the erectile function, sexual desire, sexual intercourse satisfaction, and total satisfaction in morbidly obese men. Due to limited data on body mass index and hormone levels, our meta-analysis had some limitations. More clinical studies are needed to further explore the relationship between bariatric surgery and male sexual function. Xu J, Wu Q, Zhang Y, et al.
