Abstract
Introduction The age at the onset of juvenile idiopathic arthritis (JIA) can influence the trajectory of the disease. We aimed to clarify how age at the visit 6 months after the onset as a continuous variable affects long-term remission of JIA.Methods This study investigated 358 patients from the Nordic JIA cohort study. Age at diagnosis was analysed continuously. Three age groups were studied: under 3 years, 3–5 years and over 6 years of age. JIA was categorised as oligoarthritis, seronegative polyarthritis and others (enthesitis-related, psoriatic and undifferentiated arthritis). Clinical da
