Difference of the cytokines level between the NSCD and SCD group at baseline. Violin plots were used to visualize the distribution of numerical data and depicted summary statistics and the density of each variable. Abbreviation: pg/ml: picograms per milliliter; FGF basic: basic fibroblast factor; INF-γ: interferon gamma; IL-1β: interleukin-1 beta; SCF: stem cell factor; MCP-1: monocytechemoattractantprotein-1; M-CSF: macrophage colony-stimulating factor; IL-9: interleukin-9; PDGF-BB: platelet-derived growth factor BB; RANTES: regulated on activation, normal T cell expressed and secreted. *Significantly difference (p < 0.05)
