ASC-US: atypical squamous cells of undetermined significance; LSIL: low-grade squamous intraepithelial lesion; EC: endocervical curettage.

Correlation between cervical cytology and colposcopy and histological findings.
CIN1, 2, 3: cervical intraepithelial neoplasia grade 1, 2 and 3; ASC-US: atypical squamous cells of undetermined significance; LSIL: low-grade squamous intraepithelial lesion. (*) Two cases with inconclusive biopsies (1 ASC-US and 1 LSIL) were excluded.

hr-HPV test according to the colpo-histological diagnosis.
HPV-16: positive cytological samples for subtype HPV-16. HPV-18: positive cytological samples for subtype HPV-18. Twelve Other HPV subtypes: positive cytology samples for one or more subtypes of HPV belonging to group 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66 and 68. CIN 1, 2, 3: cervical intraepithelial neoplasia grade 1, 2 and 3.
