Biological and social reproductive factors and late-life cognitive function in middle-aged and older Chinese women.
Article in Alzheimer's & dementia : the journal of the Alzheimer's Association, 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
introductionFew studies have concurrently examined the biological and social reproductive factors in relation to women's cognitive aging.
methodsWe analyzed 8577 women and 7872 men ≥45 years of age from the China Health and Retirement Longitudinal Study. Biological reproductive factors included reproductive span, age at menarche, and age at menopause; social reproductive factors included number of children and age at first live birth. Multivariable regression models were sequentially adjusted for age, childhood cognition proxy, education, and current health and lifestyle factors.
resultsLonger reproductive span was associated with better cognitive performance in women, whereas a higher number of children were linked to poorer cognition in both sexes, particularly in women. These associations remained robust after full adjustment, compared with age at menarche, age at menopause, and age at first birth.
conclusionIntegrating biological and social reproductive factors provides insights into sex-specific cognitive aging patterns and may inform tailored dementia prevention strategies. HIGHLIGHTS: A longer reproductive span was linked to better cognition in older Chinese women. More children were linked to poorer cognition in both sexes, especially in women. Reproductive span and number of children showed robust associations with late-life cognition, stronger than other reproductive factors.
