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

backgroundPolycystic ovary syndrome (PCOS) is the most common metabolic disorder among women of reproductive age. Many factors are involved in the development of PCOS, among which genetic predisposition is probably the main contributor that is also influenced by lifestyle and environmental factors. This study aims to determine the prevalence of PCOS in different continents based on Rotterdam, AES and NIH diagnostic criteria.

methodsWe conducted a systematic review and meta-analysis to evaluate the prevalence of polycystic ovary syndrome in women according to (Preferred Reporting Items for Systematic Review and Meta-Analysis) PRISMA guidelines. PubMed, Scopus, Science Direct, Web of Science and Google Scholar databases were comprehensively searched until February 2021 for relevant articles. Heterogeneity between the studies was assessed using the I

resultsA total of 35 studies with 12,365,646 subjects were retrieved. The mean age ranged from 10-45 years. Global prevalence of PCOS was 9.2% (95% CI: 6.8-12.5%) based on meta-analysis, our results showed that the global prevalence of PCOS was 5.5% (95% CI: 3.9-7.7%) based on NIH criteria, 11.5 (95% CI: 6.6-19.4) based on Rotterdam criteria, and 7.1% (95% CI: 2.3-20.2%) based on AES criteria. According to self-report subgroup analysis, the prevalence of PCOS was found to be 11% (95% CI: 5.2-21.8%).

conclusionBased on the results of the present study, the prevalence of PCOS in the world was 9.2% (95% CI: 6.8-12.5%). According to the results of the present study and the high prevalence of PCOS, especially in the Africa continent, it is necessary for health systems to implement measures to timely prevent and treat this syndrome.
