a DDS levels [low (1–6), medium (7–12), and high (13–18)] were defined according to practical implications for public health. b Tertile 1 of E-DII ranged from −5.44 to −0.49; tertile 2 of E-DII ranged from −0.50 to 1.12 and from 1.13 to 4.65 in UK Biobank. c RERI (95% CIs) values were calculated based on the reference group with tertile 3 of E-DII and low-level DDS. RERI values equal to 0, less than 0, and more than 0 indicate no, negative, and positive additive interaction, respectively. Abbreviations: CIs: confidence intervals; DDS, dietary diversity score; E-DII, dietary inflammatory index; RERI, the relative excess risk due to interaction.
