Exclusion criteria
Exclusion criteria: 1. Not called for screening, ie ages under 30 years, or over 60 years 2.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome measure of POBASCAM trial is the occurrence of histologically confirmed CIN3 lesions or (micro-) invasive carcinoma of the cervix found during the time span from intake up to and including the next screening round, i.e., in five years. Since women with normal cytology at the next screening round will not be referred for colposcopically-directed biopsies and therefore will not have a histological endpoint, it will be assumed that no precursor lesions of cervical cancer are present. This policy complies with regular cervical screening in The Netherlands. | — |
Secondary
| Measure | Time frame |
|---|---|
| As a secondary outcome measure, histologically confirmed cervical intraepithelial neoplasia grade 2 will also be investigated, since current guidelines recommend ablative treatment for these lesions as well. Other secondary parameters obtained include progression and regression of cytology diagnoses, clearance and acquisition of hrHPV infections and the number of referrals for colposcopically-directed biopsies. | — |
