Prevalence of different HPV genotype infections. (A) HPV-16 is most prevalent genotype in HPV-positive women. (B) The HR-HPV infection rate showed a bimodal trend, and the rates of different age groups were statistically significant (χ²=272.740; p<0.001). Top 5 most frequent HPV genotypes in (C) NILM patients; (D) LSIL (CIN1) patients; (E) HSIL patients (CIN2 and CIN3); and (F) cervical cancer. Orange bar in (C-F) is the cumulative cases of HPV genotypes.

CIN, cervical intraepithelial neoplasia; HPV, human papillomavirus; HR-HPV, high-risk human papillomavirus; HSIL, high-grade squamous intraepithelial lesion; LSIL, low-grade squamous intraepithelial lesion; NILM, negative for intraepithelial lesion or malignancy.
