Values are presented as number (%). Detected by PCR-RDB genotyping, 18 HR-HPV, and 5 LR-HPV subtypes could be analyzed in the population.
HPV, human papillomavirus; HR-HPV, high-risk human papillomavirus; LR-HPV, low-risk human papillomavirus; PCR-RDB, polymerase chain reaction-reverse dot blot.
*Dual-type infection: patients with 2 HPV subtypes infection simultaneously; †Multi-type infection: patients with 3 or more HPV subtypes infection simultaneously; ‡Represented the percent of HPV-positive patients in different age groups.
