Anal and oral human papillomavirus (HPV) infection in HIV-infected subjects in northern Italy: a longitudinal cohort study among men who have sex with men

Table 3 Persistence of HPV in the anal area according to the risk level of the viral genotype.

HPV genotypes are grouped by oncogenic risk or are indicated as negative HPV samples. LR: low-risk; undetermined: undetermined-risk; possible HR: possible high-risk; HR: high-risk. Table cells contain counts, i.e., numbers of patients. The rate (percentage) of persistence is indicated by oncogenic risk. No difference was detected among the various rates (Pearson's Chi² (3) = 0.1397, P-value = 0.987).
