At 95% sensitivity the corresponding specificity is given and vice versa. AUC (area under the curve) indicates diagnostic accuracy. Threshold values are the number of Ki-67 immunopositive cells/1000 cells. | |||
ASCUS, atypical squamous cells of undetermined significance; CI, confidence interval; HSIL, high grade squamous intraepithelial lesion; LSIL, low grade squamous intraepithelial lesion; ROC, receiver operating characteristic. | |||
