Clinically inactive disease (CID) was defined at each time point using the 2004 Wallace criteria (no active joints, no fever/rash/serositis/splenomegaly/lymphadenopathy, no active uveitis, normal ESR/CRP, physician’s global assessment (PGA) indicating no disease activity), with modifications that reflected the core clinical outcomes seen in systemic JIA. This evidence concerns the gene CRP and uveitis.
