Epidemiologic Characterization of Human Papillomavirus Infection in Rural Chaozhou, Eastern Guangdong Province of China
Figure 5
Simple/multiple infection composition.
A: Simple/multiple infection constituent ratio of HR-HPV subtypes. B: The case numbers of infection frequency. The case number sharply decreased with the increasing of infection frequency. C: Linear regression relationship between multiple infections constituent ratio and age. The mean age of each group was 37.82±1.31, 42.47±1.47, 47.17±1.33, 52.60±1.41 and 57.13±1.43 years, respectively. The multiple infections constituent ratio increased with age. D: The age-related multiple infections constituent ratio in 4 different areas. The multiple infections constituent ratio increased with age for women who lived in the suburban, plain and mountain. For those lived at the seashore, there was an incidence peak in age from 50 to 55 group. E: The multiple infections constituent ratio in 4 different areas. There was no significant difference in 4 areas. F: The percentage of multiple infections of the 6 most common HR-HPV subtypes in 5 different age groups. G: The percentage of multiple infections of the 6 most common HR-HPV subtypes in 4 different area groups.
