Clinical factors associated with cognitive impairment in cerebral small vessel disease: a retrospective study.
Article in BMC neurology, 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
backgroundCerebral small vascular disease (CSVD) has an insidious onset and progresses slowly, leading to cognitive impairment. Understanding the clinical characteristics of cognitive impairment is crucial for early identification, prevention, and treatment. This study aimed to analyze risk factors associated with cognitive impairment related to CSVD.
methodsThis retrospective study included 270 patients with CSVD and independent living abilities. Laboratory tests included measurements, such as fasting blood glucose (FBG), glycosylated hemoglobin, and blood creatinine. All patients underwent neuropsychological evaluation, and the main factors influencing cognitive impairment were analyzed using multivariate logistic regression.
resultsAmong the patients, 80% (n = 216) had symptomatic cerebral infarction. Factors such as history of symptomatic cerebral infarction, FBG level, blood fibrinogen level, and CSVD total burden score were significantly different between the normal cognition and cognitive impairment groups (p < 0.001, p = 0.049, p = 0.009, p = 0.001, respectively). Logistic regression analysis revealed that age, FBG level, and number of lacunar cerebral infarctions were the main factors influencing cognitive impairment. Age, education level, fibrinogen and d-dimer levels, and CSVD total burden score significantly correlated with the level of cognitive impairment. Impaired daytime function affected the cognitive levels of patients with CSVD (p = 0.043).
conclusionsThis study has highlighted the main risk factors for cognitive impairment in patients with CSVD, such as age, FBG levels, and number of lacunar cerebral infarctions. Additionally, education played a significant role in cognitive outcomes. These findings suggest that managing these risk factors and enhancing cognitive reserve can mitigate the cognitive decline associated with CSVD.
