Fig. 3

The effect of E-DII in 2011 on LDA or less at 2011. Data were analyzed with multivariable logistic regression analysis, and results were shown as forest plot of the odds ratio for low disease activity (LDA; DAS28-ESR ≤ 3.2) or less at 2011. The forced-entry method was used for the seven covariates shown in the figure. E-DII score was divided by 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
