Subcortical brain volumetric differences related to white matter lesion volume and cognition in healthy aging.
Article in npj aging, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
White matter hyperintensity (WMH) lesions associated with small vessel cerebrovascular disease (CVD) are common structural neuroimaging findings in older adults. Greater global brain WMH burden related to aging has been implicated in dementia but has also been linked to brain atrophy and cognitive dysfunction in old age. We sought to investigate the regionally distributed association of global WMH lesion load with subcortical gray matter (SGM) volumes using a multivariate network analysis method in 178 community-dwelling, healthy older adults (mean age = 69.77 ± 10.22 years). We additionally applied mediation models with WMH-related subcortical volumetric differences as a mediator to evaluate a potential global WMH-related vascular risk pathway leading to cognitive aging. Global WMH burden was associated with a regionally distributed pattern of SGM atrophy involving bilateral putamen and left nucleus accumbens, with relative volume increases in bilateral caudate nucleus. Mediation analyses revealed that increasing age predicted greater WMH-SGM pattern expression, which then predicted slowed processing speed that was, in turn, associated with decrements in other age-sensitive cognitive domains of memory, executive functioning, and fine motor function. These results suggest that the multivariate WMH-SGM pattern and its association with processing speed may provide an important early indicator of age-related decrements in higher-order cognitive processes, reflecting a potential link between CVD and broader cognitive dysfunction across multiple domains in healthy aging.
