ADAMTS5 and juvenile idiopathic arthritis: We recorded significant relationships between HA and TGF-β levels (r = −0.813, p = 0.014), as well as insignificant relationships with ADAMTS4 (r = −0.139, p = 0.701), ADAMTS5 (r = −0.475, p = 0.196) and TOS (r = 0.388, p = 0.390) in JIA patients before ETA treatment.
