Development of pial collaterals by extension of pre-existing artery tips.
Article in Cell reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Pial collaterals provide protection from ischemic damage and improve the prognosis of stroke patients. The origin or precise sequence of events underlying pial collateral development is unclear and has prevented clinicians from adapting new vascularization and regeneration therapies. We use genetic lineage tracing and intravital imaging of mouse brains at cellular resolution to show that during embryogenesis, pial collateral arteries develop from extension and anastomoses of pre-existing artery tips in a VegfR2-dependent manner. This process of artery tip extension occurs on pre-determined microvascular tracks. Our data demonstrate that an arterial receptor, Cxcr4, earlier shown to drive artery cell migration and coronary collateral development, is dispensable for the formation and maintenance of pial collateral arteries. Our study shows that collateral arteries of the brain are built by a mechanism distinct from that of the heart.
