↵* The functional scale used was the Juvenile Arthritis Functionality Scale (JAFS) for correlations with 21-circle VAS and the Childhood Health Assessment Questionnaire (CHAQ) for correlations with horizontal VAS.
↵† The HRQOL measure used was the Pediatric Rheumatology Quality of Life scale (PRQL) for correlations with 21-circle VAS and the Child Health Questionnaire (CHQ) for correlations with horizontal VAS. MD: physician; HRQOL: health-related quality of life; ESR: erythrocyte sedimentation rate; CRP: C-reactive protein; VAS: visual analog scale.
