Rypdal V, et al. - Researchers attempted to formulate the prediction rules that could guide early treatment decisions based on baseline clinical predictors of long-term unfavorable outcome in juvenile idiopathic arthritis (JIA). Data disclosed the presence of functional disability in 111/340 (32.7%) children assessed by CHAQ and 40/199 (20.1%) by Physical Summary Score (PhS), and joint damage was found in 29/216. Yielded results illustrated the feasibility of making long-term predictions of JIA outcome based on early clinical assessment. It was also deduced that the prediction models presented acceptable precision and warranted only readily available baseline variables.
