  1. ACPA anticitrullinated protein antibodies, CI confidence interval, CRP C-reactive protein, DMARD disease-modifying antirheumatic drug, ESR erythrocyte sedimentation rate, HAQ health assessment questionnaire, HR hazard ratio, RF rheumatoid factor, SJC swollen joint count, TJC tender joint count
  2. *p < 0.05
  3. aThe multivariable model includes all variables that showed a significant association with sustained DMARD-free remission in univariable Cox regression analyses. A total of 224 patients were included in the multivariable model since data on the tested variables were incomplete for 14 patients. No statistically significant differences were present between patients with missing data and the patient included in the multivariable model (data not shown)
