↵# A validated composite disease measure specifically developed for juvenile idiopathic arthritis and ranges from 0 (inactive disease) to 30, composed of the active joint count (maximum 10 joints), and physician global and parent global disease activity evaluation. VAS: visual analog scale; cJADAS10: Clinical Juvenile Arthritis Disease Activity Score; CRP: C-reactive protein; ESR: erythrocyte sedimentation rate; IQR: interquartile range.
