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
Introduction: This study examines the burden of six gynecological system diseases (uterine fibroids, polycystic ovarian syndrome, endometriosis, cervical cancer, ovarian cancer, and uterine cancer) in Chinese women aged 15-49 years from 1990 to 2021. Methods: This research used data on the incidence and disability-adjusted life-years (DALYs) of six gynecological diseases from the GBD 2021 study. The Joinpoint Regression Program 5.2.0 was employed to analyze age-standardized incidence rates (ASIR), DALY rates, and estimated annual percentage change (EAPC). Results: In China, uterine fibroids had the highest ASIR (271.82/100,000), while cervical cancer had the highest age-standardized DALY rate (117.11/100,000). Between 1990 and 2021, polycystic ovarian syndrome (PCOS) exhibited the fastest ASIR growth (EAPC=1.62) and DALY rate (EAPC=2.09), while cervical cancer incidence also rose (EAPC=1.24). The burden showed distinct age-specific patterns: Uterine fibroids had the fastest growth in age-standardized DALY rate (EAPC=1.46). PCOS was concentrated in the 15-19 age group and showed the fastest growth (ASIR 317.17/100,000, EAPC=1.96). Ovarian cancer showed the largest increases in low‑middle SDI regions (ASIR EAPC=1.69; age-standardized DALY rate EAPC=1.29). Conclusion: The burden of six gynecological diseases among Chinese women of reproductive age varies significantly by age and time. Cervical cancer causes the most severe health loss. Polycystic ovarian syndrome demonstrates a prominent burden among younger women with a clear upward trend. Notably, China faces accelerated growth in both polycystic ovary syndrome and uterine fibroids, while ovarian cancer showed the largest increases in low-middle SDI regions. Finding provide essential evidence to guide age-tailored prevention, early detection, and resource allocation strategies in China and other countries undergoing similar epidemiological transitions.
