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
JOURNAL/nrgr/04.03/01300535-202606000-00055/figure1/v/2026-02-11T151048Z/r/image-tiff Vascular cognitive impairment and dementia is a debilitating neurological disorder caused by chronic cerebral hypoperfusion, for which no effective causative treatments are currently available. Intermittent hypoxia has been shown to enhance cerebral blood flow in mice, but its efficacy in a model of vascular cognitive impairment and dementia remains unclear. In this study, we established a mouse model of vascular cognitive impairment and dementia by bilateral carotid artery stenosis. Intermittent hypoxia was induced before and after this stenosis. We found that intermittent hypoxia increased cerebral blood flow, oxygen saturation, and microcirculation in the prefrontal cortex and hippocampus in the model mice, without causing neurovascular damage. Additionally, intermittent hypoxia significantly improved cognitive function in the mouse model of vascular cognitive impairment and dementia, with perconditioning showing greater efficacy than preconditioning. Improvements in cerebral microcirculation and blood flow were positively correlated with cognitive recovery. Even in a mouse model of vascular cognitive impairment and dementia with comorbidities induced by a high-fat, high-fructose diet, intermittent hypoxic perconditioning demonstrated protective effects on cognitive function. Proteomic analysis indicated that mitochondrial protection is a key mechanism, particularly through upregulating NDUFB8 expression and increasing the activity of mitochondrial complex I. These findings suggest that intermittent hypoxia is a potential non-invasive strategy for the prevention and treatment of vascular cognitive impairment and dementia.
