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

backgroundMorbid obesity has been known to decrease fertility in both men and women. This review aimed to examine current evidence of the effects of bariatric surgeries on fertility parameters including sex hormones in both men and women, seminal outcomes in men, menstrual cycle, PCOS symptoms, and pregnancy in women, and sexual function in both men and women.

methodsThree databases (PubMed, Web of Science, and Academic Search Premier) were used with key terms of bariatric surgery, bariatric surgical procedures, infertility, reproductive health, pregnancy, and fertility. Studies with male and/or female patients were included. Study types included retrospective chart reviews, observational, qualitative, cross-sectional, cohort, and longitudinal studies published in January 2008-June 2018. The search was performed on June 21-26, 2018. Quality assessment and data synthesis were conducted.

resultsA total of 18 articles were included in the final review. Seven studies included only men, ten included only women, and one included both men and women. Bariatric surgery significantly improved hormonal balance and sexual functions in both males and females, sperm count in males, and pregnancy in females. The strongest evidence was found on bariatric surgery's effects on sex hormones. No study with males asked whether the participants actually conceived a child with their partners after the bariatric surgery. Most weaknesses in all articles reviewed were lack of discussion on confounding variables and many did not differentiate surgical types.

conclusionBariatric surgery most effectively improved sex hormones. Further research is needed on direct pregnancy outcomes for both men and women.
