	Responsiveness				Discriminative ability
	SRM	Effect size	Guyatt		Correlation method		AUC-ROC:c value (95% CI)
	SRM	Effect size	Physician	Parent	Physician	Parent	Physician	Parent

SRM, standardised response mean; AUC ROC, area under the curve of the receiver operating characteristic; LROM, limited range of motion; GASS, Global Articular Severity Score; CHAQ, Childhood Health Assessment Questionnaire; CHQ, Child Health Questionnaire; ESR, erythrocyte sedimentation rate.
