Values are the adjusted mean ± SE, unless indicated otherwise. All mean values are adjusted for the baseline value of the dependent variable and group assignment. For use of disease‐modifying antirheumatic drugs (DMARDs), raw percentages are shown. Frequencies and percentages are averaged across 50 imputations used to estimate values for missing data. The average frequencies are rounded to the nearest integer. 95% CI = 95% confidence interval; RA = rheumatoid arthritis; SMART = Strategic Memory Advanced Reasoning Training.
