Association of Increased Brain Iron Levels With Anxiety and Motor Dysfunction in Cerebral Small Vessel Disease.
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
aimsThis study explored the relationships between brain iron levels, emotion, and cognitive and motor function in cerebral small vessel disease (CSVD) patients using quantitative susceptibility mapping (QSM).
methodsA total of 208 subjects were enrolled in this study. A brain QSM map was calculated from multiecho GRE data via morphology-enabled dipole inversion with an automatic uniform cerebrospinal fluid zero reference algorithm (MEDI+0). Multiple linear regression analysis was applied to explore the clinical factors influencing cerebral susceptibility in CSVD patients. Correlation analysis and pathway-specific mediation effects between brain iron levels and motor function were investigated.
resultsThere were significant differences in the MoCA scores, depression scores, five-repetition sit-to-stand test (5R-STS) time, and susceptibility values of the caudate nucleus and putamen among the three groups (p < 0.05, FDR correction). Age and history of diabetes played crucial roles in brain iron levels in the caudate nucleus and putamen, which may increase iron levels in the basal ganglia, associated with cognitive decline. Notably, the susceptibility values of the left caudate nucleus and putamen were positively correlated with the 5R-STS time in CSVD subjects, and there were significant mediating effects of anxiety on the prediction of motor dysfunction with respect to iron levels in the left putamen in CSVD patients.
conclusionAge, diabetes status, and anxiety may serve as effective intervention targets for individuals with CSVD, especially individuals with cognitive and motor dysfunction. A greater brain iron burden may be a quantitative imaging marker of cognitive and motor dysfunction in CSVD patients.
