| Protein carbonyls (nmol/l) | -0.614 | <0.001* | -0.197 | 0.242 |
| Superoxide dismutase activity (U/gmHb) | 0.803 | <0.001* | -0.280 | 0.094 |
| Glutathione peroxidase activity (mU/mL) | 0.755 | <0.001* | -0.232 | 0.168 |
| Oxidant/ anti-oxidant ratio | -0.790 | <0.001* | -0.022 | 0.895 |
| Copper (μmol/l) | 0.817 | <0.001* | -0.210 | 0.211 |
