Hormone Therapy is Associated with Better Cognitive Performance in Postmenopausal Women: Insights from the National Health and Nutrition Examination Survey (NHANES).
Article in Annals of geriatric medicine and research, 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
backgroundAlzheimer's disease is more prevalent among females. Estrogens influence brain metabolism and function, and low blood levels before, during, and after menopause may be associated with cognitive decline in later years. Here, we investigate the association between hormone therapy and reproductive lifespan with cognitive performance using a nationally representative sample from the National Health and Nutrition Examination Survey (NHANES) database.
methodsThis cross-sectional study included 1,374 eligible women aged 60 years or older from the NHANES database. Cognitive performance was assessed using the Consortium to Establish a Registry for Alzheimer's Disease (CERAD) word learning subtest, the Animal Fluency Test (AFT), and the Digit Symbol Substitution Test (DSST). Univariate analysis and multivariate logistic regression were employed to evaluate the association between hormone therapy, reproductive span, and cognitive performance. Restricted cubic spline curves were used to assess the relationship between age as a continuous variable and cognitive performance.
resultsAfter adjusting for age, race, and educational level, hormone therapy was significantly associated with word recall, digit symbol, and animal fluency cognitive performance (p < 0.05). The reproductive span was associated with word recall performance (p = 0.027) but not with digit symbol or animal fluency. The age-related cognitive decline is attenuated by hormone therapy with maximum effect between 65 and 70 years for all dimensions.
conclusionThere is a positive association between hormone therapy and cognitive performance in postmenopausal women, particularly in age groups with the steeper decline. In addition, there is no significant association between reproductive span and cognitive function.
