Key mechanisms of angiogenesis in the infarct core: association of macrophage infiltration with venogenesis.
Article in Molecular brain, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Angiogenesis in the ischemic penumbra compensates for microcirculatory dysfunction and promotes neuronal plasticity after stroke. However, the current understanding may be highly biased because the contribution of veins to angiogenesis has been overlooked. This study revealed that the remodeling processes of veins differ from those of arteries after ischemia. Ligation of the right jugular vein increased the infarct volume, decreased cerebral blood flow and impaired long-term functional restoration after stroke. RNA-seq analysis revealed significant upregulation of the expression of genes associated with angiogenesis in the infarct core during the recovery period. By using gelatin ink-alkaline phosphatase-oil red O (GIAO) staining, we found that venogenesis, the process of creating new veins, was the predominant angiogenic event in the infarct core. Macrophage infiltration and transformation are closely associated with venogenesis in the infarct core. However, depletion of macrophages in the circulation by clodronate liposomes in the acute phase inhibited the proliferation of endothelial progenitor cells and decreased the vascular density in the infarct core. This study demonstrated that dynamic vein remodeling is crucial for cerebral ischemic damage and subsequent neuronal restoration. Angiogenesis occurs in the infarct core during the recovery period, promotes the absorption of necrotic tissue and facilitates functional recovery after stroke.
