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

Background: Early vascular regeneration is important for the speedy recovery of neurological function following ischemic stroke. M2-like microglia polarization decreases and vascular regeneration weakens with aging. The function of mitochondrial respiratory chain is dependent on M2-like polarization in microglia. Methods: A murine model of middle cerebral artery occlusion (MCAO) was used to perform animal behavioral assessments, immunoblotting, tube formation and chick embryo chorioallantoic membrane assays. A D-galactose-induced cellular senescence model was established in BV2 cells. Results: Aging significantly exacerbates acute brain injury 24 hours post-cerebral ischemia-reperfusion, with increased expression of M1-like microglial markers and a concomitant decrease in M2-like microglial markers. Additionally, aging can inhibit DARS2 protein expression, adversely affect angiogenesis and reduce brain-derived neurotrophic factor (BDNF) and vascular endothelial growth factor A (VEGFA) expression. In vitro, oxygen-glucose deprivation/reoxygenation and re-glucose (OGD/R) demonstrated that Conclusion: This study suggests that aging impedes M2-like microglial polarization by downregulating DARS2 expression in microglia, thereby impairing emergency angiogenesis during acute ischemic stroke and exacerbating neuronal damage.
