BTG3 and juvenile idiopathic arthritis: Ocular involvement was found to be more frequent in females (73.0 vs. 62.9%, p = 0.03), in ANA-positive patients (60.3 vs. 37.0%, p < 0.001), and in patients with younger age at disease onset (5.3 ± 4.1 vs. 9.3 ± 4.4 years, p < 0.001), demonstrating that the main features of children with JPsA who develop uveitis are similar to those of children with uveitis in other JIA categories [30].
