Association of blood urea nitrogen to albumin ratio with cerebral small vessel disease and its ischemic imaging markers: a cross-sectional study.
Article in Frontiers in neurology. 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: This study aims to assess the association between blood urea nitrogen to albumin ratio (BAR) and cerebral small vessel disease (CSVD) and its common ischemic neuroimaging markers, including white matter hyperintensities (WMH), enlarged perivascular spaces (EPVS), and lacunes. Methods: This cross-sectional study involved 762 participants, including 452 patients with CSVD and 310 non-CSVD controls. Their clinical data, hematological markers, and neuroimaging results were collected. The relationship between the BAR index and CSVD/ischemic neuroimaging markers was assessed using Spearman's rank correlation coefficient, multivariable logistic regression, and restricted cubic splines. Subgroup analyses were performed stratified by various covariates. Model performance and calibration were evaluated using ROC analysis, bootstrap validation, and calibration curves. Sensitivity analyses were conducted to assess the robustness of associations against varying levels of kidney function. Results: After adjusting for confounding factors, BAR was positively associated with CSVD (OR: 1.77, 95% CI: 1.35-2.33, Conclusion: BAR is independently associated with CSVD and its ischemic imaging markers, highlighting its potential as a novel and cost-effective biomarker. These findings warrant further investigation to determine its utility for risk stratification and its potential role in primary care screening protocols.
