CIN1, cervical intraepithelial neoplasia grade 1; CIN2+, cervical intraepithelial neoplasia grade 2 or worse; HPV, human papillomavirus; HR-HPV, high-risk human papillomavirus.
*The sum of the percentages of each HPV type is not necessarily equal to 100% because a result may be counted more than once in cases where the sampled lesion contained multiple HPV types; †Proportion of multiple attributable fraction and number of single infection within HR-HPV positive women.
