MDA, malondialdehyde; ox-LDL, oxidized low-density lipoprotein; DTAC, dietary total antioxidant capacity; OBS, oxidative balance score; PI, phytochemical index. Adjusted for age, energy intake, BMI, sex, physical activity, and smoking history. Obtained by linear regression. Significant values are shown in bold.
