Shortened Relative Leukocyte Telomere Length Is Associated With Polycystic Ovary Syndrome and Metabolic Traits.
Article in Endocrinology, diabetes & metabolism, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundPolycystic ovary syndrome (PCOS) is one of the commonest gyneco-endocrine disorders amongst women of reproductive age. Whether PCOS and cardiometabolic traits in PCOS patients are associated with shortened telomere length (TL) or relative leukocyte telomere length (rLTL) remains unclear.
methods214 women with PCOS and 214 age-matched women were recruited. rLTL was measured with an updated quantitative real-time PCR protocol and reported as ΔΔCt between telomere and a single-copy gene encoding β-globin relative to a normalisation control. A two-way Mendelian randomization analysis using the UK Biobank Resource was performed to assess the causal relationship between rLTL and PCOS.
resultsWomen with PCOS had significantly shortened rLTL (PCOS: 0.5 ± 0.7; control: 0.8 ± 0.6; p < 0.001). Longer rLTL was associated with a lower risk of PCOS after adjusting for age, history of smoking and other cardiometabolic traits (OR: 0.503; 95% CI: 0.342-0.730; p < 0.001). Longer rLTL was associated with reduced risk of dyslidpidemia (OR: 0.563; 95% CI: 0.450-0.968; p = 0.042) in PCOS patients. PCOS subjects with rLTL shorter than mean of the rLTL of control subjects had an elevated risk of dysglycemia (OR: 2.09; 95% CI: 1.04-4.29; p = 0.040). No causal relationships were found between rLTL and PCOS in the Mendelian randomization study.
conclusionsWomen with PCOS have significantly reduced rLTL and shorter LTL may be associated with cardiometabolic risk factors in PCOS subjects. There are no causal relationship between genetically determined PCOS and TL or vice versa.
