  1. 1 Results of univariate Cox proportional hazard models with baseline predictors for time-to-DAS remission (disease activity score, DAS<1.6) up to three years of follow-up, given with hazard ratios (HR) and 95% confidence intervals (95%CI). 2 Results of the final multivariate Cox proportional hazard prediction model with independent baseline predictors for the time-to-remission (disease activity score, DAS<1.6) up to three years of follow-up, given with hazard ratios (HR) and 95% confidence intervals (95%CI).
  2. RF = rheumatoid factor; DAS = disease activity score based on 53 tender joint counts (TJC) and 44 swollen joint counts (SJC); HAQ = health assessment questionnaire; Dis = disease; ESR = erythrocyte sedimentation rate; VAS = visual analogue scale; GH = general health. Age was measured in years and disease duration in weeks.
