The effect of changes in E-DII on maintenance of LDA or less over 6-year period. Data were analyzed with multivariable logistic regression analysis, and results were shown as forest plot of the odds ratio for maintenance low disease activity (LDA; DAS28-ESR ≤ 3.2) or less for a 6-year period from 2011 to 2017. ΔE-DII indicates the change of the score from 2011 to 2017. The forced-entry method was used for the seven covariates shown in the figure. ΔE-DII score was divided by change value positive or negative (i.e., positive as referent). bDMARDs, biological disease-modifying antirheumatic drugs; BMI, body mass index; CCP, cyclic citrullinated peptide antibody; CI, confidence interval; DAS28-ESR, disease activity score with 28 joint using erythrocyte sedimentation rate; E-DII, energy-adjusted dietary inflammatory index; OR, odds ratio
