Abbreviation: DII, dietary inflammatory index.

^a DII scores ranged from −4.08 to 4.08

^b Adjusted for age, education, total energy, body mass index, number of pregnancy, contraceptive use, lactation, smoking, and family history of breast cancer.

^*p‐value for trend derived using the median approach.
