Impact of cardiometabolic factors and AD plasma biomarkers on white matter hyperintensities volume in individuals with cognitive complaints from the global south.

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 hyperintensities (WMH) are a magnetic resonance imaging (MRI) sign associated with cognitive complaints in the Alzheimer's Disease (AD) continuum, including the pre-dementia steps. Cardiovascular and neurodegenerative pathophysiology have been postulated as relevant factors in the origin of WMH in AD. However, this evidence comes mainly from northern global populations, where the epidemiological profile differs from other geographical regions. This study explores the relationship between WMH, cardiometabolic and plasma neurodegeneration biomarkers in individuals with cognitive complaints from a developing country in the global south, where cardiometabolic risk factors are highly prevalent. We analyzed 112 individuals with cognitive complaints, assessing plasma pTau217, Aβ42/Aβ40 ratio, blood pressure, and glycemia levels while quantifying and segmenting WMH volumes. Multiple regression analyses revealed that diastolic blood pressure was significantly associated with WMH in specific white matter tracts, including the anterior thalamic radiation, cingulum, forceps minor, and subcortical regions. In contrast, no associations were found with glycemia, pTau217, Aβ42/40, or systolic blood pressure. These findings suggest that cardiovascular factors could be more critical in WMH development than neurodegeneration markers in this population. Our study, in addition to reflecting, in part, the associations between cardiovascular risk factors and WMH, highlights the need for further research on neurovascular contributions to dementia pathophysiology in these populations, emphasizing the role of neurovascular integrity, blood-brain barrier function, and cerebrospinal fluid circulation in underrepresented geographical contexts.
