There are 2 ages missing.
Cytologies taken within the previous 6 months to the cancer diagnosis were excluded for the analysis because they were considered as part of the diagnostic process. There are 2 women with a nonevaluable previous cytology. These cases were excluded for the analysis in which result of previous cytology is involved.
^aPercentages of specific cytological abnormalities are among the abnormal cytologies.
FIGO: International Federation of Gynecology and Obstetrics, ASC-US: atypical squamous cell of undetermined significance, ASC-H: atypical squamous cells cannot exclude a high grade squamous intraepithelial lesion, AGC: atypical glandular cells of undetermined significance, LSIL: low grade squamous intraepithelial lesion, and HSIL: high grade squamous intraepithelial lesion.
