  1. Values are mean (± SD) unless otherwise indicated; n numbers, VAS visual analog scale
  2. aSelf-reported body pain intensity during the last 4 weeks, measured with SF-36 questionnaire, 1–6 (1 = no pain, 6 = very severe pain)
  3. bSelf-reported pain influence on daily activities during the last 4 weeks, measured with SF-36 questionnaire, 1–5 (1 = not at all, 5 = extremely)
  4. cSelf-reported current joint-related pain the day of visit, measured with 10 cm continuous VAS (0 = no pain, 10 = unbearable pain). One of 33 participants with active disease did not fill in the VAS current joint-related pain
  5. dSelf-reported disease-related pain last week measured with 21 numbered 0–10 VAS (0 = no pain, 10 = unbearable pain)
  6. eDisease status according to the definition by Wallace et al. Remission off med. remission off medication for ≥ 12 months. Inactive disease inactive disease on medication for less than 6 months or inactive disease off medication for less than 12 months or remission on medication (inactive disease on medication for more than 6 months). Active disease flare or continuous active disease
