Endothelial stem cells of the retinal vasculature reside in the optic nerve.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Cells of the retina, photoreceptors especially, are highly metabolically active with substantial energy requirements. Accordingly, the effective delivery of oxygen and nutrients to the retina via the retinal vasculature is key to tissue function. Indeed, a disturbed retinal blood supply, especially if prolonged, can result in a loss of vision. Vascular endothelial cells, which form the inner lining of blood vessels, are pivotal in ensuring a healthy blood circulation in many tissues, including the light-sensitive retina at the back of the eye. However, the mechanism by which vascular endothelial cells maintain a functional retina (and aid the healing of a damaged one) is not understood. Here, through single-cell RNA sequencing, colony-forming assays and lineage tracing analysis, we provide data that point to a new regulatory system by which vascular endothelial cells are supplied to the retina by a reservoir of stem/progenitor cells in the optic nerve.
