title: Remission in rheumatoid arthritis: agreement of the disease activity score (DAS28) with the ARA preliminary remission criteria.
abstract: OBJECTIVE
  To determine which cut-off point in the RA disease activity score (DAS28) corresponds to fulfilment of the ARA criteria for clinical remission.
  
  
  METHODS
  The disease activity of patients included in the Nijmegen RA inception cohort was systematically assessed every 3 months. For all visits, a modification of the ARA preliminary criteria for clinical remission was applied and the DAS28 was calculated. Receiver operating characteristic analysis was used to determine the cut-off point with maximum sensitivity and specificity in DAS28 corresponding with fulfilment of the modified ARA criteria.
  
  
  RESULTS
  Three hundred and seventy-eight patients contributed 4378 visits. In 6.5% of the visits four of the five items and in 1.5% all five items of the modified ARA criteria were fulfilled. The optimal cut-off point for the DAS28 that corresponds to fulfilment of the modified ARA criteria was determined to be 2.66.
  
  
  CONCLUSIONS
  DAS28 <2.6 corresponds to fulfilment of the preliminary ARA criteria for clinical remission in RA.
