Fig. 3From: Impaired training-induced angiogenesis process with loss of pericyte-endothelium interactions is associated with an abnormal capillary remodelling in the skeletal muscle of COPD patientsCorrelations between morphologic markers of the angiogenic process and clinical and functional parameters of COPD patients and SHS. Positive significant correlations between the proportion of capillary profiles associated with Pc/EC interdigitations in post-training vastus lateralis biopsies and a forced expiratory volume in 1 s (FEV1) (% predic.), b post-training values of symptom-limited oxygen uptake (\( \mathrm{V}\dot {\mathrm{O}}_{2\mathrm{sl}} \)), in both COPD patients (grey circles) and SHS (white circles)Back to article page
