  • Comedication is defined as medication started for juvenile idiopathic arthritis within 30 days before start of MTX and until the end of the observation period. In case of missing items forming part of the decision for the ACR-CPG, it was analysed if it could have altered that decision in any way; only if so, the case was marked missing for such a decision.

  • ACR-CPG, American College of Rheumatology clinical practice guideline; anti-TNF, anti-tumour necrosis factor therapy; CRP, C reactive protein; ESR, erythrocyte sedimentation rate; IA, intra-articular; OJIA, oligoarticular juvenile idiopathic arthritis; PJIA, polyarticular course juvenile idiopathic arthritis; VAS, Visual Analogue Scale.
