Values indicated are mean (SD). Except where indicated otherwise, means of each variable before and after anakinra were compared by a non-parametric Wilcoxon test.
*Estimated by parents for SoJIA patients and by patient for AoSD patients.
‡Means were compared by t test. p Values <0.05 were considered significant.
†Latest follow-up: 14.7 (2–27) months in SoJIA patients and 14.3 (2–27) in AoSD patients.
§In mg/kg/day in SoJIA patients and in mg/day in AoSD patients.
AoSD, adult-onset Still disease; CHAQ, Childhood Health Assessment Questionnaire; CRP, C-reactive protein; ESR, erythrocyte sedimentation rate; SoJIA, systemic-onset juvenile idiopathic arthritis; VAS, visual analogue scale.
