The relationship between HPV infection groups and DNA heteroploid

Type of HPV infection	DNA ploidy					Chi-square test
	Positive	Negative	Positive rate (%)	OR	95% CI	${\chi }_{\text{MH}}^2$	P
Negative HPV infection	2	51	3.77	–	–	–	–
Non-high-risk HPV infection	3	18	14.29	4.250	0.656–27.524	–	0.135*
Single high-risk HPV infection	38	76	33.33	12.750	2.945–55.204	17.355	<0.001**
Multiple high-risk HPV infection	65	73	47.10	22.705	5.316–96.972	31.566	<0.001**

Notes:

^*Compared with the negative group; P>0.05, has no statistical significance.

^**Compared with the negative group, P<0.05, all have statistical significance.
