What is more, we recorded insignificant correlations between PIICP and CRP (r = −0.303, p = 0.104) as well as PIICP and ESR (r = 0.299, p = 0.108) in treated patients with JIA whose clinical condition had stabilized (A’, i.e., inactive disease). The gene discussed is CRP; the disease is juvenile idiopathic arthritis.
