Independent Role of White Matter Hyperintensity Volume and Location in Alzheimer's Disease Risk Beyond Hippocampal Atrophy.
Article in Psychiatry investigation, 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
objectiveIncreases in white matter hyperintensities (WMH) observed on brain MRI are associated with the onset of Alzheimer's disease (AD) and cognitive decline. Recent hypotheses suggest that the impact of WMH on cognition may differ by their distance from the ventricular surface. This study aimed to investigate the effects of WMH volume and location, classified by distance from the ventricular surface, on cognitive function in individuals with AD.
methodsA total of 112 normal cognition (NC) individuals and 171 patients with AD underwent clinical evaluation, volumetric MRI, and neuropsychological testing using the Korean version of the Consortium to Establish a Registry for Alzheimer's Disease. WMH volume was categorized as juxtaventricular (JVWMH, <3 mm from ventricle), periventricular (PVWMH, 3-13 mm), and deep (DWMH, >13 mm).
resultsThe mean WMH volume was significantly higher in AD group (20.7±18.2 mL) than in the NC group (6.8±8.1 mL, p<0.001). A tenfold increase in WMH volume led to a 5.967-fold increased risk of AD (95% confidence interval [CI]=1.550-22.986). A similar risk association was observed for PVWMH (OR=4.021, 95% CI=1.592-10.156), and DWMH showed a significant risk association (OR= 2.873, 95% CI=1.227-6.731). Total WMH, JVWMH, and PVWMH were associated with poorer performance in verbal fluency and memory tasks, while DWMH showed no significant cognitive association.
conclusionWMH volume and location independently contribute to AD risk and cognitive decline, with PVWMH and JVWMH particularly affecting executive and memory functions, regardless of hippocampal atrophy.
