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

backgroundProcesses related to how the intracranial microvasculature initiates brain‒peripheral crosstalk for subsequent blood‒brain barrier (BBB) dysfunction at an early stage after subarachnoid hemorrhage (SAH) ictus are still unknown. This study elucidated the effect and potential mechanism of intracranial microvasculature-mediated T-cell infiltration on BBB function after SAH.

methodsPublicly available single-cell RNA sequencing data related to SAH ( https://ngdc.cncb.ac.cn/omix ; Accession No. OMIX006611) were retrieved and analyzed. The dataset was derived from the white matter region of adult male C57BL/6J mice at 1 and 7 days after experimental SAH. The SAH model was induced by endovascular perforation, and experiments were subsequently conducted at 1, 3, 7, and 14 days after SAH to evaluate T-cell infiltration, BBB integrity, neuronal injury, and neurological function.

resultsAfter SAH, CXCL12 expression was increased in endothelial cells and pericytes, promoting CD8

conclusionThis study suggests that, following SAH, both pericytes and endothelial cells may contribute to immune regulation by producing CXCL12, which promotes CD8⁺ T-cell infiltration into the brain. This mechanism may play a role in BBB disruption and neurological dysfunction. Targeting the CXCL12-CXCR4 axis could offer a potential approach for mitigating immune-mediated injury after SAH.
