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.
All the variables are adjusted by area and groups of age.
ASC-US: atypical squamous cell of undetermined significance, ASC-H: atypical squamous cells which 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.
