Risk stratification of posttreatment cervical intraepithelial neoplasia grade 2+ (CIN 2+) provided by carcinogenic human papillomavirus (HPV) testing, cytology, and surgical margin histology. In each test method of high-risk HPV testing, cytology (atypical squamous cells of undetermined significance+) or surgical margin histology, the absolute risks of having recurrent or residual CIN 2+ lesions (
) and 95% confidence intervals (error bars) were calculated for women testing positive or negative for each test. HPV testing provided the greatest risk stratification between test-positive and -negative women.
