  1. Abbreviations: N Number, CHAQ Childhood Health Assessment Questionnaire (0 = no physical disability, 3 = maximal physical disability), VAS pain Visual analogue scale for self-reported pain (0 = No pain, 10 = maximal pain) reported by the patient/parent on a 21-numbered circle VAS, PhysGA Physician's global assessment of disease activity (0 = No activity, 10 = high activity) reported by the physician on a 21-numbered circle VAS, RF Rheumatoid factor
  2. aNumber of participants assessed for each variable, excluding missing/unknown values. Total participants, N = 221
  3. bNot in remission = Patients who do not fit the criteria for “Remission off medication” (inactive disease off medication for >12 months) as defined by Wallace et al.
  4. cCalculated using the formula: Weight (kilograms)/[height (metres)]2 and subsequently adjusted for age and sex according to The International Obesity Task Force (IOTF) cut-off values to allow for comparison with adult BMI groups as defined by Cole TJ, et al.: Underweight: <18.5, normal weight: 18.5-24.9, overweight/obese: ≥25 kg/m2
