Persistent and sequential human papillomavirus (HPV) infections and clearance of HPV infection related to evidence of cervical cytological dyskaryosis at follow up
| Follow up cervical cytology result (total no.) | HPV type specific persistent infection | Sequential HPV infection | Clearance of HPV infection | Untypeable* HPV infection |
|---|---|---|---|---|
| *3 specimens were HPV positive at baseline and follow up but could not be assigned to either HPV persistent or sequential infections because the specific HPV type could not be determined; therefore, they were excluded from subsequent analysis. | ||||
