Heterogeneity of Systemic Oxidative Stress Profiles in COPD: A Potential Role of Gender

Figure 5

Relationships between systemic lipid peroxidation and (a) muscle mass index (kg/m²) and (b) 6-MWD (% pred.). (a) Systemic lipid peroxidation, expressed in μmol/L, was significantly and negatively correlated with muscle mass index (; ) in 54 COPD patients. (b) Systemic lipid peroxidation, expressed in μmol/L, was significantly and negatively correlated with 6-MWD (; ) in 54 COPD patients.
