A
The cell was blank if the original study did not give the respective information.
B
Some studies detected cervical lesions using histology or cytology testing method. Abnormalities in histology were cervical intraepithelial neoplasia 1, 2 and 3; abnormalities in cytology were low-grade squamous intraepithelial lesion and high-grade squamous intraepithelial lesion.
