Associations of biomarkers of cellular senescence with physical and cognitive function among older women with or without a history of premenopausal bilateral oophorectomy.
Article in Maturitas, 2025. 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
objectivesTo study whether a history of premenopausal bilateral oophorectomy (PBO) may influence circulating concentrations of cellular senescence biomarkers and their associations with measures of physical and cognitive function later in life. STUDY
designThe plasma concentrations of 29 candidate senescence biomarkers and parameters of physical and cognitive function were measured in 510 older women, comprising 273 with a history of PBO and 237 referents.
main outcome measuresPlasma concentrations of senescence biomarkers and their associations with measures of physical and cognitive function.
resultsIn participants with a history of PBO compared to referents, only the plasma levels of tumor necrosis factor alpha (TNFα) and tumor necrosis factor receptor 2 (TNFR2) were statistically significantly higher than they were in the referent group, whereas matrix metalloproteinase 2 (MMP2) was lower. Overall, measures of physical and cognitive function did not differ between those with and without PBO. In an exploratory analysis, several senescence-related biomarkers were associated with chronological age, body mass index, and measures of physical function, including 6-minute walk distance and muscle strength and power. Only few biomarkers were associated with measures of cognitive function. Using machine learning, subsets of biomarkers in combination with demographic and clinical covariates exhibited higher value than the covariates alone in predicting most of the physical and cognitive function outcomes in cross-sectional analyses.
conclusionsThe circulating concentrations of several candidate senescence biomarkers were associated with physical and cognitive function in a cohort of older women, but only a few biomarkers differed between participants with a history of PBO and referents. Additional research is needed to better understand the influence of PBO on the biology of aging.
