Figure 1

Cumulative probability of clearance of incident HPV infection, by viral group and age group (under 30 years and 30 years and over), in women with normal cytology at baseline. Number of infections (n) with point estimates and 95% CI of median duration of infection by age group are reported. HPV16 persisted significantly longer in women under 30 years of age than older women (P<0.01, log-rank test).
