Ref=reference level.a Time-averaged over four study visits.b Adjusted for positivity to the other HPV genus, age, lifetime number
of sex partners, any sex in last interval, and new sex in last
interval.c Positive for any type of the other HPV genus at same
visit; corresponds to betapapillomavirus positivity for columns where
alphapapillomavirus prevalence is the outcome, and alphapapillomavirus
positivity for columns where betapapillomavirus prevalence is the
outcome.
