Logistic regression models were used to obtain the OR of breast cancer risk, with 95% CIs in tertile of flavonoids and phenolic acids subclasses.
OR, odds ratio; CI, confidence interval.
*Additionally adjusted for menopausal status, cancer family history, day bra wearing, physical activity (MET-h/day), vitamin D supplement, total energy intake (kcal/day), body mass index and total fiber intake (g/d).
