Enlarged Perivascular Spaces Among Hispanic and Latino Adults in SOL-INCA-MRI.
Article in Journal of the American Heart Association, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundTo examine preliminary associations between enlarged perivascular spaces (ePVS) and cerebrovascular small-vessel disease, cortical atrophy, and cognitive impairment among a select cohort of Hispanic and Latino adults. The Hispanic and Latino population has a higher prevalence of dementia and vascular disease but is underrepresented in dementia research. This study addresses this gap by investigating ePVS in a large convenience cohort of Hispanic and Latino individuals.
methodsBrain magnetic resonance images from a convenience sample of 2161 participants, including 28.8% of individuals aged >50 years with cognitive impairment from the SOL-INCA-MRI (Study of Latinos-Investigation of Neurocognitive Aging Magnetic Resonance Imaging) study were analyzed. ePVS volume in the cerebral white matter was quantified using an automated method and then residualized with total cerebral volume. Associations between residualized mean ePVS volumes and demographic factors, magnetic resonance imaging measures, and cognitive impairment were assessed using regression models.
resultsResidualized mean ePVS volume was significantly associated with age (
conclusionsThis convenience sample of Hispanic and Latino individuals demonstrates significant associations between ePVS volume and established markers of cerebrovascular small-vessel disease, cortical atrophy, and cognitive impairment. These findings suggest that ePVS may be useful as an additional marker of vascular brain injury within this cohort.
