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.
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 and metabolic disorder affecting adolescent girls globally. Despite its prevalence, the global burden of adolescent PCOS has not been systematically assessed. This study aims to evaluate the worldwide impact of PCOS among adolescents from 1990 to 2021 and forecast its future trajectory using data from the Global Burden of Disease (GBD) Study 2021. Methods: We analyzed trends in incidence, prevalence, and disability-adjusted life years (DALYs) associated with adolescent PCOS using GBD 2021 data. The analysis was stratified by age, socio-demographic index (SDI), and geographic region. Temporal trends were assessed using the estimated annual percentage change (EAPC). Health inequality analysis and frontier analysis were applied to examine disparities and identify potential for burden reduction. An autoregressive integrated moving average model was used to forecast the future burden of adolescent PCOS from 2022 to 2041. Results: The global age-standardized incidence rate of adolescent PCOS increased from 268.64 per 100,000 in 1990 to 348.21 per 100,000 in 2021 (EAPC: 0.81%). The prevalence rate rose from 1176.61 per 100,000 to 1526.36 per 100,000 (EAPC: 0.89%), and the DALYs rate increased from 10.53 to 13.62 per 100,000 (EAPC: 0.88%). Health inequality analysis revealed a widening gap between high- and low-SDI regions, with a disproportionate concentration of burden in higher-SDI countries. Frontier analysis identified countries like Italy and Japan as having greater potential for burden reduction. Southeast Asia exhibited the most rapid growth, with EAPCs exceeding 2.4%-approximately three-fold higher than the global average. Conclusion: The global burden of adolescent PCOS has steadily increased from 1990 to 2021, with significant regional disparities. The widening health inequality and rapid growth in Southeast Asia underscore the urgent need for targeted public health interventions. The projected rise in burden underscores the urgent need for targeted public health interventions, especially in regions with rapid increases in incidence and prevalence.
