NILM: Negative for intraepithelial lesion or malignancy; ASC-US: Atypical squamous cells of undetermined significance; LSIL: Low grade squamous intraepithelial lesion; ASC-H: Atypical squamous cells, rule out HSIL; HSIL: High grade squamous intraepithelial lesion; HR-HPV: high-risk HPV; Cervical Intraepithelial Neoplasia: CIN.
α5: HPV51; α6:HPV53,56,66; α7:HPV18,39,45,59,68; α9:HPV16,31,33,35,52,58.
The total outnumbers the different combinations identified because different types are counted more than once between rows.
