Plasma 4-HNE concentrations in COPD patients and control subjects. Plasma 4-HNE was measured via ELISA and compared in different groups. (A) Plasma 4-HNE concentrations in the three groups (n = 150 for control subjects; n = 150 for AECOPD patients; n = 80 for SCOPD patients). (B) Plasma 4-HNE concentrations in AECOPD patients with different grades. (C) Plasma 4-HNE concentration in AECOPD patients with different mMRC scores. (D) Plasma 4-HNE concentrations in AECOPD patients with different CAT scores. (E) Plasma 4-HNE concentrations in AECOPD patients with different CCQ scores. *P < 0.05, **P < 0.01.
