Bold values represent significant differences with P < 0.05.

Model 1: crude model. Model 2: adjusted for sex, race, smoking status, and drinking status. Model 3: as model 2 and additionally adjusted for age and BMI.

DII = dietary inflammatory index; Q1 = low DII; Q2 = medium-low DII; Q3 = medium-high DII; Q4 = high DII.
