  1. The prevalence of one HPV subtype in ICC is significantly different from that of in precancerous cervical lesions (CIN I, χ2 = 61.57, P < 0.001; CIN II, χ2 = 19.88, P < 0.001); except CINIII (CIN III, χ2 = 2.74, P = 0.098)
  2. The prevalence of monotypic HPV infection was significantly higher than that of polytypic HPV infection in each group of patients with cervical lesions, P < 0.001 (CIN I, χ2 = 135.40; CIN II, χ2 = 45.92; CINIII, χ2 = 111.69; ICC, χ2 = 137.21)
