The correlation of TGF-β1, FGF10, and PDGF expression and the patients’ survival rate. (A,B) Lower expression of PDGF was closely associated with better survival rate of INSIP rather than IPF patients (*P<0.05); (C-F) the relationship between differential expression level of TGF-β1, FGF10 and the survival time of IPF and INSIP patients, there no statistical significance among these groups. TGF-β1, transforming growth factor-beta-1; FGF10, fibroblast growth factor 10; PDGF, platelet derived growth factor; IPF, idiopathic pulmonary fibrosis; INSIP, idiopathic nonspecific interstitial pneumonia.
