To read the full abstract: Pediatr Rheumatol Online J. 2017Aug 22;15(1):68This large prospective study analysed growth in children with JIA during a 3-year period from diagnosis. Interesting findings emerge: the heights and weights of these patients, clearly compromised in historical cohorts, appeared nearly normal. Increased risk of growth impairment was noted in patients with systemic arthr...
