The Relationship Between Glymphatic Function, White Matter Hyperintensity and Cognition: A Structural Equation Model MRI Study.
Article in CNS neuroscience & therapeutics, 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
backgroundWhite matter hyperintensity (WMH) is associated with glymphatic dysfunction. Few studies have focused on the causal effects of the dysfunction of the glymphatic circulation pathways (inflow and outflow pathway) on WMH and cognitive function.
methodsThis study investigated the directional effects between glymphatic circulation, WMH lesions, and cognitive function in older adults based on structural equation models. The lateral ventricle choroid plexus (ChP), the coupling strength between blood oxygen signals in gray matter and cerebrospinal fluid flow, the diffusion tensor imaging analysis along the perivascular space (DTI-ALPS) index, and meningeal lymphatic vessels (MLVs) were analyzed for quantitative analysis of the glymphatic circulation.
resultsCompared to healthy controls, participants with WMH had greater ChP volume, lower DTI-ALPS index, and reduced MLVs function, all associated with worse cognitive performance. Both ChP/LatVent (p = 0.009) and DTI-ALPS (p < 0.001) are significant predictors of WMH volume. Deep WMH (DWMH) partially mediated the relationship between glymphatic function (ChP/LatVent, β = 0.108, p = 0.044; DTI-ALPS, β = 0.122, p = 0.032) and cognition. Structural equation models revealed that glymphatic outflow negatively influenced WMH (β = -0.572, p < 0.001), and WMH had a significantly negative effect on cognitive function (β = -0.705, p = 0.006).
conclusionsOur results suggest that DWMH plays a mediating role in glymphatic decline and cognitive abnormalities, and that diminished glymphatic circulation affects WMH volume, leading to decreased cognitive function.
