  1. Values are presented as estimated means ± standard error from the repeated-measures analyses of variance
  2. P values are for the interaction between groups over time (from baseline to 3 months) as calculated with the use of repeated-measures analyses of variance (with baseline DAS28-CRP as a covariate)
  3. Abbreviations: 6MWT 6-min walking test
  4. *Significant difference to baseline p<0.05 (repeated measures ANOVA)
  5. **Significant difference to baseline p<0.01 (repeated measures ANOVA)
