Includes participants who had at least one interpretable (β-globin positive) anal sample for any of the two HPV genus types tested (β-HPV and γ-HPV gamma)

The following variables had missing values: age (4 missing); age at sexual debut (4 missing); number of lifetime sexual partners (6 missing)

Adjusted for age, age at sexual debut, and number of lifetime sex partners
