Figures & data

Figure 1. HPV genotype distribution in the HPV-positive patients and the physical examination group, the cervicitis group, and the cervical cancer group. (a) HPV52, HPV16, HPV58, HPV81, and HPV53 were the most predominant genotypes in the HPV-positive patients. (b) HPV52, HPV16, HPV58, HPV81, and HPV53 were the main type of HPV infections in all the three groups (the physical examination group, the cervicitis group, and the cervical cancer).

Table 1. Genotype distribution of HPV infection in the physical examination group, the cervicitis group, and the cervical cancer group.

Single HPV genotype infection	65.2(%)	61.6 (%)	70.9(%)
Multiple HPV genotype infection	34.8(%)	38.4(%)	29.1(%)	0.0275
