Objective. To compare the safety and efficacy of parenteral methotrexate (MTX) at an intermediate dosage (15mg/m(2)/week) versus a higher dosage (30 mg/m(2)/ week) in patients with polyarticular-course juvenile idiopathic arthritis (JIA) who failed to improve while receiving standard dosages of MTX (8-12.5 mg/m(2)/ week).
