¹ Data are expressed as the values of correlation coefficient (r) and the level of statistical significance (p). The values of r with p < 0.05 were considered statistically significant (* p < 0.05, ^† p < 0.01, ^‡ p < 0.001). NS—not statistically significant (p > 0.05). SOD, superoxide dismutase; CAT, catalase; GPx, glutathione peroxidase; GR, glutathione reductase; TSH, total thiol groups; PSH, protein thiol groups; GSH, reduced glutathione; GSSG, oxidized glutathione; TAS, total antioxidative status; H₂O₂, hydrogen peroxide; MPO, myeloperoxidase; TOS, total oxidative status; OSI, oxidative stress index; LPO, lipid peroxides; MDA, malondialdehyde; PC, protein carbonyls.
