  • A DAS28 score greater than 5.1 is considered to be indicative of high disease activity
  • Between 5.1 and 3.2 indicates moderate disease activity
  • Less than 3.2 indicates slow disease activity
  • A patient scoring less than 2.6 is defined as being in remission

The European League Against Rheumatism (EULAR) response criteria are based on the DAS measure:

  • a decrease in DAS28 score of 0.6 or less is considered to show a poor response, while decreases greater than 1.2 points indicate a moderate or good response, dependent on whether an individual’s DAS28 score at the end point is above or below 3.2 respectively
