Correlations between airway mitochondrial membrane potential and FEV1, TLCOc and VO2 Peak. (a) Correlations between airway mitochondrial membrane potential (ΔΨm) and FEV1 (% predicted), (b) single-breath transfer factor of the lung for carbon monoxide (TLCOc % predicted), (c) six-minute walk distance (6 MW), and (d) weight-adjusted peak oxygen uptake (VO2 peak ml/min/kg). ● never-smokers (n = 5), ■ ex-smokers (n = 8) and ▲COPD GOLD Grade 2 (n = 6)
