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

Background: Polycystic Ovary Syndrome (PCOS) is a common endocrine disorder affecting adolescent and young adult females, yet global data on its burden and trends remains limited. Methods: We analyzed data from the Global Burden of Disease Study 2021 for females aged 10-24 years in 204 countries (1990-2021). Metrics included cases, age-standardized incidence (ASIR), prevalence (ASPR), disability-adjusted life years (ASDR), and average annual percentage changes (AAPCs). Future trends (2022-2036) and disease reduction gaps were assessed. Results: From 1990 to 2021, global PCOS cases increased by 56% (incidence), 59% (prevalence), and 58% (DALYs). ASIR rose from 49.45 to 63.26 per 100,000, with an AAPC of 0.8. Southeast Asia, East Asia, and Oceania had the fastest growth, while high-SDI regions bore the highest burden. Girls aged 10-14 showed the steepest age-specific increase. Nationally, the largest increases occurred in Equatorial Guinea, Maldives, and Myanmar, while Italy saw a decline. Forecasts through 2036 indicate continued increases in ASIR (+8.32%), ASPR (+10.87%), and ASDR (+10.39%). Frontier analysis highlighted unachieved reduction potential, especially in high-SDI countries. Conclusions: PCOS burden among adolescents and young adults has significantly risen globally with disparities by region, SDI, and age, warranting urgent and equitable public health strategies.
