Weighted prevalences of any HPV, any high-risk HPV, and one or more vaccine-type HPV infections by school grade.

Note: Weighted prevalences were calculated by adjusting for sampling ratios in general high schools and vocational schools using Horvitz-Thompson adjustment. Confidence intervals (CI) were calculated using the Wilson score method. For HPV prevalences, including low-risk HPV types, Horvitz-Thompson adjustment was used for extrapolation to entire samples, based on available results. (a) Any HPV infection ..÷ positive for any one or more of the following HPV types: HPV16, 18, 26, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66, 68, 69, 73, 82, 11, 40, 42, 43, 44, 54, 6, 61, 70. (b) Any high-risk HPV infection ..÷ positive for any one or more of the following HPV types: HPV16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, 68. (c) Positive for any one or more of HPV16, 18, 6, 11, 31, 33, 45, 52, 58. (d) Positive for any one or more of HPV 16, 18, 6, 11. (e) Positive for any one or more of HPV 16, 18.
