IL10 and polyarticular arthritis: To study whether the IL-17A and IL-10 polymorphisms were associated with disease activity, the patients with oligoarthritis or polyarthritis were divided into four groups (inactive disease, low disease activity, medium disease activity, and high disease activity) on the basis of their JADAS10 scores, as defined by Consolaro et al. [33,34], at two different time points: at diagnosis and at 1 year after diagnosis.
