1 · What the graph read from it

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.

2 · The registry

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

Intracranial and extracranial arterial stenosis, the primary cause of chronic cerebral hypoperfusion (CCH), is a critical reason for the pathogenesis of vascular dementia and Alzheimer's disease characterized by cognitive impairments. Our previous study demonstrated that limb remote ischemic conditioning (LRIC) improved cerebral perfusion in intracranial arterial stenosis patients. The current study aimed to test whether LRIC promotes angiogenesis and increases phosphorylated endothelial nitric oxide synthase (p-eNOS) activity in CCH rat model. Adult male Sprague-Dawley rats were randomly assigned to three different groups: sham group, bilateral carotid artery occlusion (2VO) group and 2VO+LRIC group. Cerebral Blood Flow (CBF) was measured with laser speckle contrast imager at 4 weeks. Cognitive testing was performed at four and six weeks after 2VO surgery. We demonstrated that LRIC treatment increased cerebral perfusion and improved the CCH induced spatial learning and memory impairment. Immunohistochemistry confirmed that LRIC prevented cell death in the CA1 region, and increased the number of vessels and angiogenesis in the hippocampus after 2VO. Western blot analysis shows that LRIC therapy significantly increased p-eNOS expression in the hippocampus when compared with 2VO rats. Moreover, eNOS inhibitor reduced the effect of LRIC on angiogenesis in the hippocampus and spatial learning and memory function. Our data suggested that LRIC promoted angiogenesis, which is mediated, in part, by eNOS/NO.
