title: Paediatric rheumatology: A disease activity index for juvenile SpA-a welcome addition.
abstract: A lack of universally accepted classification criteria for patients with juvenile spondyloarthritis (SpA) has hindered efforts to develop tools to assess the severity and progression of this disease. With the publication of a new juvenile SpA disease activity index, has this gap now been bridged, and is it a comprehensive tool for the clinic?
