Greater White Matter Hyperintensities and More Severe Cognitive Dysfunction in Mild Cognitive Impairment With Motoric Cognitive Risk Syndrome.
Article in Journal of Korean medical science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThe motoric cognitive risk syndrome (MCRS) is characterized by slow gait and cognitive complaints. A motor-based approach to MCRS provides a clinical strategy for identifying individuals at high risk for dementia.
methodsThis study included 81 outpatients with mild cognitive impairment (MCI). All participants underwent clinical evaluations, including volumetric brain magnetic resonance imaging (MRI) and neuropsychological testing with the Korean version of the Consortium to Establish a Registry for Alzheimer's Disease Assessment Packet. White matter hyperintensities (WMH) volume was calculated using automated segmentation analysis from three-dimensional MRI images. MCRS was defined by the presence of cognitive complaints and slow gait defined as gait speed at least one standard deviation below age- and sex-specific means.
resultsA total of 31 subjects with MCRS and 50 subjects without slow gait participated in this study. The linear regression analysis revealed a significant negative relationship between WMH volume and gait speed in both the MCI group with MCRS (β = -1.010,
conclusionMCRS represents a distinct and more severe clinical entity within the MCI population, characterized by greater cognitive impairment and increased WMH burden.
