HPV genotype point prevalence (95% confidence interval), and number of infections at all visits after reported first sex in 105 adolescent girls.
The HPV genotype-specific point prevalence was estimated as the number of visits where the genotype was detected, divided by the total number of visits after the reported date of sexual debut, including the enrolment visit. Visits with missing vaginal samples, or with samples that were β-globin negative, are excluded.
