Mean instrument scores at baseline and mean score differences between the baseline and 6 month evaluation

	Mean baseline value (SD)	Mean change (SD)	External criterion (physician)			External criterion (parent)
	Mean baseline value (SD)	Mean change (SD)	Improved (n = 23)	Stable (n = 14)	Worsened(n = 7)	Improved(n = 27)	Stable (n = 13)	Worsened(n = 4)
^*Score range: 0, best to 10, worst; ^†the articular indices refer to the injected joints only. LROM, limited range of motion; GASS, Global Articular Severity Score; CHAQ, Childhood Health Assessment Questionnaire (score range: 0, best to 3, worst); CHQ, Child Health Questionnaire (mean (SD) norm based score for both physical and psychosocial scores: 50 (10)); ESR, erythrocyte sedimentation rate.
