Figure 2. Cumulative incidence rates of high-grade squamous intraepithelial lesions (HSIL) according to the HPV genotypes.

Women with HPV-positive and cytology-negative results were classified into 4 groups depending on the HPV genotype detected on the first examination. Significant differences in the incidence of HSIL were found between the 4 groups. Note that there is a higher risk of development of HSIL in women with HPV-58 infection.
