Fig. 1: Age-specific prevalence of HPV according to different tests. HCII = hybrid capture II test, used only for carcinogenic HPV types; PCR-ONC = polymerase chain reaction test for carcinogenic HPV types; PCR-ANY = polymerase chain reaction test for any HPV type. The data are based on results for 824 women who tested positive for β-globin (i.e., specimens contained intact DNA).
