From: Preserved function and reduced angiogenesis potential of the quadriceps in patients with mild COPD
Individual values of quadriceps mRNA expression for vascular endothelial growth factor A (VEGF-A, panel A), angiopoietin I (Ang I, panel B) and angiopoietin II (Ang II, panel C) in patients with mild COPD ( open dots ) and controls ( filled dots ). The horizontal lines represent group mean values. *Indicates statistically significant difference between the two groups (see text for exact p values).
