Table 1 Participant characteristics according to the presence/absence of HR-HPV at baseline and follow-up. Medians and interquartile ranges (interquartile range in brackets), means and standard deviations (standard deviations preceded by “±”) as well as absolute and relative frequencies (relative frequencies indicated by “%”) are presented. Group comparisons between negative/positive individuals at baseline and negative/positive individuals at follow-up were conducted using Mann Whitney U tests, independent t tests, Chi-squared tests, and Fisher’s exact tests
