- Legend: Multivariable logistic regression models in ACPA-negative RA (n = 184) with SDFR (yes/no) as dependent outcome variable. Multivariable analysis showed DAS levels at 4 months (DAS4 months) were as predictive of SDFR as decrease in ΔDAS0–4m, with and without incorporation of baseline DAS in the model
- DAS disease activity score, BL baseline, CI confidence interval
