BTG3 and uveitis: Among the different groups, we observed that patients with JIA-associated uveitis were significantly younger (p = 0.025) and more frequently have anterior uveitis (χ2 8.44, p = 0.004), while patients with idiopathic uveitis were less frequently ANA-positive (χ2 6.69, p = 0.035), they more frequently had ocular symptoms at onset (χ2 13.87, p < 0.001), and more complications compared to the other groups (p < 0.001) (Table 1).
