CIN cervical intraepithelial neoplasia, NR never or rarely (not screened within 5 years) screened, P5Y screened within last 5 years

p values significantly different at <0.05 from separate nested logistic models of CIN3 or worse, with age, race/ethnicity, residence, or region associated with screening history

Percentages age-adjusted to the 2000 National Breast and Cervical Cancer Early Detection Program

CIN3 or worse includes CIN3, carcinoma in situ, adenocarcinoma in situ, and invasive cervical cancer
