Updated Overview of the Geographical Prevalence of Polycystic Ovary Syndrome by Diagnostic Criteria, Phenotypes, Race, and Ethnicity.
Review in International journal of environmental research and public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundNewly named Polyendocrine Metabolic Ovarian Syndrome (PMOS), previously Polycystic Ovary Syndrome (PCOS), affects women worldwide. The prevalence of PCOS is thought to range from 5 to 15% depending on the diagnostic criteria used. The 2023 International Evidence-Based Guidelines for the Assessment and Management of PCOS recognize the 2003 Rotterdam criteria as the gold standard diagnostic tool. The objective was to examine the global prevalence of PCOS across diagnostic criteria, phenotypes, geographical locations, races, and ethnicities by reviewing current research.
methodsResearchers searched PubMed, PsycINFO, and Scopus. The study included 27 articles.
resultsPrevalence varies globally, ranging from 1.6% to 28.5% in North America. In Brazil, the prevalence was 30.4%. Europe showed rates ranging from 5.9% to 19.9%. In Asia, the prevalence ranged from 4.21% in rural India to 35.3% in the Kashmir Valley. Oceania showed a prevalence of 6.8% among Samoan women and 12% in Australian women. The Middle East ranged from 1.6% in Dubai to 48.5% in Pakistan. In Africa, the prevalence was 32.5% in Sudan.
conclusionsThe study's findings highlight significant variations in the prevalence and phenotype distributions influenced by demographic factors and diagnostic criteria. Limitations include inconsistent diagnostic criteria, underrepresentation of geographical regions, and reliance on self-reported data, emphasizing the importance of using standardized diagnostic criteria and focused research.
