Linking atrial fibrillation to cerebral small vessel disease: a cross-sectional study with predictive analytics.
Article in Frontiers in cardiovascular medicine, 2026. 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
Background: Atrial fibrillation (AF) and cerebral small vessel disease (CSVD) are prevalent in older adults and may synergistically contribute to cognitive decline and stroke risk. This study investigates the association between AF and CSVD markers, including white matter hyperintensities (WMHs), cerebral microbleeds (CMBs), lacunes, and silent brain infarcts, focusing on sex-specific patterns, anticoagulation status, and predictive modeling. Methods: In a cross-sectional study of 923 individuals aged ≥70 years undergoing 3.0-Tesla brain MRI, AF was identified via ECG, self-reports, and hospital records. CSVD markers were quantified using standardized MRI protocols. Regression models, adjusted for demographic and vascular risk factors, assessed associations between AF and CSVD markers, stratified by sex, anticoagulation status, and AF onset age. Random Forest and logistic regression models predicted high WMH burden and stroke risk. Results: Of 923 participants, 85 (9.2%) had AF. AF was associated with higher WMH volumes (adjusted mean: 0.0046 vs. 0.0034 mL/TIV, Conclusion: AF is independently associated with CSVD, particularly in men and anticoagulated individuals, emphasizing the need for targeted strategies to mitigate AF-related brain injury.
