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
Human dental pulp stem cells (hDPSCs) present several advantages, including their ability to be non‑invasively harvested without ethical concern. The secretome of hDPSCs can promote the functional recovery of various tissue injuries. However, the protective effects on hypoxia‑induced skeletal muscle injury remain to be explored. The present study demonstrated that C2C12 myoblast coculture with hDPSCs attenuated CoCl2‑induced hypoxic injury compared with C2C12 alone. The hDPSC secretome increased cell viability and differentiation and decreased G2/M cell cycle arrest under hypoxic conditions. These results were further verified using hDPSC‑conditioned medium (hDPSC‑CM). The present data revealed that the protective effects of hDPSC‑CM depend on the concentration ratio of the CM. In terms of the underlying molecular mechanism, hDPSC‑CM activated the Wnt/β‑catenin pathway, which increased the protein levels of Wnt1, phosphorylated‑glycogen synthase kinase‑3β and β‑catenin and the mRNA levels of Wnt target genes. By contrast, an inhibitor (XAV939) of Wnt/β‑catenin diminished the protective effects of hDPSC‑CM. Taken together, the findings of the present study demonstrated that the hDPSC secretome alleviated the hypoxia‑induced myoblast injury potentially through regulating the Wnt/β‑catenin pathway. These findings may provide new insight into a therapeutic alternative using the hDPSC secretome in skeletal muscle hypoxia‑related diseases.
