ORAC: Oxygen radical absorbance capacity; H-ORAC: Hydrophilic oxygen radical absorbance capacity; L-ORAC: Lipophilic oxygen radical absorbance capacity; T-ORAC: Total oxygen radical absorbance capacity; TE: Trolox equivalents;GAE: gallic acid equivalents; OR: Odds Ratio; CI: Confidence interval.

OR1: adjusted for age (continuous), education, race, age at menarche (continuous), menopausal status and age at menopause for postmenopausal women, parity, OC use, HRT use, BMI (continuous), tubal ligation, antioxidant supplement intake, and total calories; OR2: further adjusted for physical activity (METs), and smoking status.
