The association between obstructive sleep apnea and total cerebral small vessel disease burden-Neurovascular insights of OSA.
Article in Frontiers in neuroscience, 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
Objective: This study was conducted to assess the relationship between the severity of obstructive sleep apnea (OSA) and the total burden score of cerebral small vessel disease (CSVD), global cerebral blood flow (CBF), and cognitive function. Moreover, the internal pathway through which OSA induces cognitive impairment by affecting cerebral perfusion, and overall cerebral small vessel lesions was determined in this study. Methods: In total, 94 patients who received polysomnography (PSG) at the Mental Health Center of Inner Mongolia Autonomous Region from October 2024 to February 2026 were included in this study. Based on the apnea-hypopnea index (AHI), all individuals were classified into the control and the mild group (AHI < 15 times/h, Results: The total CSVD burden and perivascular space (PVS) score in the severe OSA group were significantly higher than those in the moderate group and the control group ( Conclusion: The severity of OSA might be related to the CSVD burden score. Neuroimaging characteristics strongly related to cognitive function in patients suffering from OSA, and abnormal global CBF may serve as a non-invasive imaging marker for evaluating neurocognitive damage.
