      Background: To characterize the existing national and multi-national registries and cohort studies in juvenile idiopathic arthritis (JIA) and identify differences as well as areas of potential future collaboration. <br> <br> Methods: We surveyed investigators from North America, Europe, and Australia about existing JIA cohort studies and registries. We excluded cross-sectional studies. We captured ...

    • Validation of prediction models of severe disease course and non-achievement of remission in juvenile idiopathic arthritis part 2: Results of the Nordic model in the Canadian cohort

Our objective was to externally validate Nordic clinical prediction models in Canadian patients with JIA. <b>Methods</b> We used data from 513 subjects ...

      Rypdal, Veronika Gjertsen; Guzman, Jaime; Henrey, A; Loughin, T; Glerup, Mia; Arnstad, Ellen Dalen; Aalto, Kristiina; Rygg, Marite; Nielsen, Susan M.; Herlin, Troels; Fasth, Anders; Berntson, Lillemor; Rypdal, Martin Wibe; Nordal, Ellen Berit (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-05)
      <i>Background</i> - Models to predict disease course and long-term outcome based on clinical characteristics at disease onset may guide early treatment strategies in juvenile idiopathic arthritis (JIA). Before a prediction model can be recommended for use in clinical practice, it needs to be validated in a different cohort than the one used for building the model. The aim of the current study was ...
