Comparison of the serum levels of the three vascular endothelial growth factor (VEGF) types in healthy volunteers and patients with idiopathic pulmonary fibrosis (IPF) and hypersensitivity pneumonitis (HP). (A) The serum VEGF-A level was significantly reduced in patients with IPF compared to healthy volunteers (p<0.05). (B) The serum VEGF-C levels were significantly elevated in patients with HP compared to those with the other groups (p<0.001). (C) The serum VEGF-D levels did not differ among the three groups. ***p<0.001, **p<0.01, *p<0.05.
