Age Specific Prevalence of hrHPV Types with 95 % CI. The cobas® 4800 system delivers hrHPV results in three categories: HPV16, HPV18, and other hrHPV. Based on these results, we divided the population into three mutually exclusive categories: (1) women positive for only other hrHPV (non-16/18 hrHPV only), (2) women positive for HPV16 and/or HPV18 (HPV16/18), and (3) women positive for HPV16 and/18 as well as another hrHPV (HPV16/18 + other hrHPV). The prevalence of these three categories by age group shows a similar bimodal distribution with increased prevalence values for the youngest and oldest women in the population
