HLA-B and anterior uveitis: We also stratified the clinical manifestations for the most common subtypes (HLA-B*51:01 and HLA-B*51:08) and found that anterior uveitis was less common in the case of B*51:01 positivity than in the case of B*51:08 positivity (24.1 and 46.1%, respectively; P < 0.05; OR 0.37; CI 0.17–0.80; Table 3).
