  • Bold font indicates a statistically significant HR.

  • *Alcohol intake was categorised by the quartile intake values among HPV-negative men and the first three quartiles were combined for the referent category. Lifetime number of sexual partners was defined as men who have sex with women and/or men.

  • †Adjusted for age, race, smoking status, ethnicity and circumcision unless otherwise noted.

  • ‡HPV 6, 11, 16 or 18 are the quadrivalent vaccine HPV types.

  • §Because of small sample size, we could not adjust for race. Adjusted for age, smoking status, ethnicity and circumcision.

  •  mPR, multivariable prevalence ratio; Qn, quartile.
