Deep Medullary Vein Integrity and Relationships with Small Vessel Disease and Interstitial Diffusivity Measures in Patients with a Recent Small Subcortical Infarct.
Article in AJNR. American journal of neuroradiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
background and purposeThe role of the venous compartment in cerebral small vessel disease has yet to be fully understood. As such, we evaluated how deep medullary vein (DMV) integrity relates to MRI-based small vessel disease severity markers and glymphatic function assessed by DTI measures in patients with a recent small subcortical infarct. MATERIALS AND
methodsWe gathered demographic, clinical, and 3T MRI imaging data from 50 patients with a recent small subcortical infarct. We evaluated the venular integrity by using 2 visual scales based on their appearance on SWI. We assessed the number of lacunes and microbleeds, white matter hyperintensities volume, perivascular spaces volume in basal ganglia and white matter, summary small vessel disease score, and brain volume. Diffusivity measures in normal-appearing white matter included free water fraction, mean diffusivity and fractional anisotropy with and without free water correction, and DTI along the perivascular spaces. After categorizing the cohort in quartiles according to both venular scores, we assessed their correlations with small vessel disease markers and diffusivity measures by using multivariable ordinal regression analyses adjusting for age, sex, smoking, and summary small vessel disease score.
resultsIn univariate analysis most of the imaging variables, except for microbleeds, perivascular spaces in white matter, and DTI along the perivascular spaces, were associated with 1 or both venular scores. In multivariate analysis, free water (OR, 1.33, 95% CI, 1.03-1.73), mean diffusivity (OR, 4.56, 95% CI, 1.32-15.81), fractional anisotropy (OR, 0.77, 95% CI, 0.63-0.93), free water-corrected mean diffusivity and fractional anisotropy (OR, 2.39, 95% CI, 1.06-5.39; OR 0.78, 95% CI, 0.65-0.94, respectively), associated with vein appearance, while only brain volume (OR, 0.48, 95% CI, 0.25-0.94), fractional anisotropy with and without free water correction (OR, 0.82, 95% CI, 0.86-0.99; OR, 0.83, 95% CI, 0.7-0.99, respectively) remained robust for vein count.
conclusionsIn patients with a recent small subcortical infarct, disruption of the DMVs, increased extracellular water, and white matter injury appear to be associated.
