BVT = Bivalent vaccine-type, QVT = quadrivalent vaccine-type, NVT = nonavalent vaccine-type. Prevalence was determined with 244 SC specimens and 230 PC specimens. Chi-square and Kappa analysis were performed with only the 266 pairs of SC and PC specimens. cSingle and multiple infections were reported as proportions aof the 109 HPV positive with SC specimens; b of the 59 HPV positive with PC specimens. d The other high-risk HPVs were HPV59, HPV45, HPV35, HPV51, HPV58; e the other high-risk HPV were HPV59; f the other high-risk HPVs were HPV59, HPV35, HPV51, HPV39; g the other high-risk HPVs were HPV51.
