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

Spinal cord injury (SCI) is a severe and complex condition that can lead to significant physical impairments and affect the life quality of patients. Neural stem cells (NSCs) transplantation holds as a promising therapeutic approach for SCI. However, the challenging post-SCI microenvironment limits NSCs effectiveness. Our current research has found that transplanted NSCs, though with lower survival and differentiation, still aided in injury repair. Hypoxia was identified as a stressor inducing the release of extracellular vesicles (EVs) from NSCs through HIF-1α/RAB17 enhancing SCI repair. By extracting and modifying these EVs derived from hypoxia treated NSCs with CAQK/Angiopep2 peptides, we were able to accurately deliver them to the injury site, enhancing recovery without relying on cell survival or differentiation. This study delved into the reparative role and underlying mechanisms of transplanted NSCs in SCI, focusing on their non-cellular contributions and developed an innovative, targeted strategy for the transplantation of EVs derived from NSCs, offering a cell-free, precision therapeutic intervention for the treatment of SCI.
