  1. The HPV 16, HPV 18 and non-16/18 HR-HPV prevalence results are expressed as percentages of positives women for unique HPV 16, HPV 18 and non-16/18 HR-HPV infections without coinfection with other HR-HPV, by specific stratum for each evaluated characteristic
  2. Bold text denotes significant p values (p < 0.05). nptrend, Chi2 test np trend, to determine proportion differences between positives and negatives groups for HPV 16, HPV 18 and non-16/18 HR-HPV, for categorical variables
