Figure 2

Prevalence of patients with plasma antioxidant deficits and elevated lipid peroxidation in 54 COPD patients. Black: patients with elevated plasma lipid peroxidation and at least one antioxidant deficit/redox imbalance. Gray: patients with only antioxidant deficit/redox imbalance. White: patients with a normal systemic oxidative stress profile.
