There were no prevalent or incident infections of HPV types 11, 26, 40, 42, 54, 56, 58, 64, 68, 69, 70, 72, 73, 82, cp6108, and is39.
Detected by swab or gargle/rinse unless otherwise indicated
Participants with any oral HPV infection at baseline were excluded from the calculation of incidence for “Any type”
Among prevalent and incident infections, respectively
Participants were excluded from the calculation of oral HPV incidence by type if they were positive for that HPV type at baseline
