Figure 2

Regression analysis performed in all COPD patients (COPD-E and COPD-B groups) and CS and CNS groups showing correlations between F2-IsoPs and MCP-1 (A), IL-2 (B), IL-1β (C), IFN-γ (D), TNF-α (E), and SOD1 (F). All inflammatory molecules correlated positively and significantly with the oxidative stress marker F2-IsoPs. SOD1 correlated inversely and significantly with the oxidative stress marker F2-IsoPs.

Note: COPD-B, COPD patients with prevalent airway disease; COPD-E, COPD patients with prevalent emphysema.

Abbreviations: CNS, control nonsmoker; COPD, chronic obstructive pulmonary disease; CS, control smoker; F2-IsoPs, F2-isoprostanes; IFN, interferon; IL, interleukin; MCP, macrophage chemotactic protein; SOD, superoxide dismutase; TNF-α, tumor necrosis factor-α.
