beta HPV seropositivity was defined as seropositive to ≥1 beta HPV types versus seronegative to all beta HPV types. beta HPV infection in eyebrow hairs was defined as DNA positivity to ≥1 beta HPV types versus DNA negativity to all beta HPV types. DNA status was defined as DNA positive to one or more beta HPV types versus DNA negative to all beta HPV types. DNA status was defined as DNA positivity to species-specific beta HPV types versus DNA negative to all beta HPV types.
