The relationship between racial discrimination and white matter among Black older adults.
Article in Neurobiology of aging, 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
Black older adults experience worse brain and cognitive aging than White older adults, on average. Racially patterned psychosocial stressors may contribute to these disparities. Maintaining white matter health is important for cognitive aging, particularly among Black older adults, and it is uniquely vulnerable to stress. Examining associations between racial discrimination and white matter may elucidate mechanisms of disparities. A sample of Black older adults in the Washington Heights-Inwood Columbia Aging project were included (N = 217). Everyday and major life discrimination were self-reported on well-validated scales. Diffusion tensor imaging quantified white matter fractional anisotropy (FA). Multivariable regressions revealed more major life discrimination was associated with lower FA in the cingulum cingulate gyrus, forceps major, forceps minor, and inferior fronto-occipital fasciculus but greater FA in the superior longitudinal fasciculus temporal projection. Everyday discrimination was not associated with FA. Findings suggest that institutional racism may have a stronger effect on white matter tracts corresponding to cognitive and emotional/affective processing than interpersonal racism. White matter health may be a mechanism through which racially patterned stressors contribute to disparities in brain and cognitive aging.
