Values are mean ± SD for the data with normal distribution and median (interquartile ranges) for the data not normally distributed. PCO: protein carbonyl; NO metabolite: nitric oxide metabolite; hs-CRP: high-sensitivity C-reactive protein; IL-6: interleukin-6; TNF-α: tumor necrosis factor-α; Vit E: vitamin E.
