Women with “no CIN” more often had DQB1*0501 (OR 0.17, 95% CI 0.04–0.81, p=0.026), DRB1*16 (OR 0.21, 95% CI 0.06–0.78, p=0.019), DQA1*0301 (OR 0.35, 95% CI 0.14–0.87, p=0.024) and DRB1*14 (OR 0.59, 95% CI 0.01–0.46, p=0.007) (Table 3). Here, HLA-DRB1 is linked to cervical squamous intraepithelial neoplasia.
