Note: Remission defined as the Clinical Disease Activity Index Score ≤2.8
Values are the mean with 95% confidence intervals.
Adjusted models included a series of five mixed model linear regression models including: practice setting (Model 1), patient demographic/socioeconomic factors (Model 2); markers of rheumatoid arthritis severity (Model 3), current rheumatoid arthritis severity treatment (Model 4) and all significant factors (p<0.05) from Models 1 through 4 (Model 5)
