Note: ASC-H = atypical squamous cells, cannot rule out a high-grade lesion, ASC-US = atypical squamous cells of undetermined significance, CI = confidence interval, HSIL = high-grade squamous intraepithelial lesion, LSIL = low-grade squamous intraepithelial lesion, OR = odds ratio.

^*Cytology with worst result between Jan. 1, 2012, and Aug. 14, 2015.

^†Control: negative cytology result.

^‡Abnormal: ASC-US, LSIL, ASC-H or HSIL.

^§Adjusted for age, income, rural/urban residency and laboratory site.

^¶Low grade: ASC-US or LSIL.

^**High grade: ASC-H or HSIL.

^††Control: negative and low-grade (ASC-US, LSIL) results.
