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
Currently, effective treatments for skeletal muscle injury remain limited. The self-repair of skeletal muscle relies on the activation and differentiation of satellite cells (SCs), which fuse with damaged myofibers to form new fibers and thereby support muscle regeneration. However, in cases of severe injury, it is difficult for muscle tissue to fully restore its original structure and function, and its regenerative capacity is often markedly reduced. Thus, there is an urgent need to develop therapies that enhance muscle repair and restore physiological function. In this study, we investigated extracellular vesicles derived from neonatal mouse skeletal muscle (NMM-EVs), which are enriched in cargo from Pax7⁺ myogenic progenitor cells. We hypothesized that NMM-EVs could enhance SC activation and improve muscle regeneration following injury. Using glycerol-induced tibialis anterior (TA) muscle injury model, we evaluated the effects of intramuscular NMM-EV administration on skeletal muscle regeneration by histological, immunofluorescence, and functional analyses. In vivo, NMM-EVs significantly promoted skeletal muscle regeneration and functional recovery, upregulated Pax7 expression, increased the cross-sectional area and muscle mass of regenerated TA, and reduced fibrosis and fat infiltration. In vitro, NMM-EVs enhanced the proliferation and myogenic differentiation of mouse SCs and increased the expression of myogenic regulatory factors at both the mRNA and protein levels. In conclusion, this study demonstrates that NMM-EVs activate SCs within injured muscle, promote their proliferation and differentiation, and thereby accelerate injury repair and myofiber regeneration while attenuating fibrotic and adipogenic remodeling. These findings provide a scientific basis for the development of neonatal muscle-derived extracellular vesicle-based, cell-free therapeutic strategies for skeletal muscle injury.
