Abstract

To create a prediction model of high-grade cervical intraepithelial neoplasia (CIN) based on clinical variables and the cervical nitric oxide metabolite (NOx) levels of study participants.This comparative study included 694 women undergoing colposcopy due to abnormal pap smear results. On the basis of the cervical biopsy results, the women were divided into the a parts per thousand currency signCIN 1 or CIN 2-3 group. The two groups were compared in terms of cervical NOx levels and clinical variables. Univariate, multivariate, and receiver-operating characteristic curve analysis were performed.Multivariate analysis showed that CIN 2-3 associated with more than two cervical biopsies [odds ratio (OR) = 5.16], high-grade squamous intraepithelial lesion cytology (OR = 16.19), condom non-use (OR = 4.28), cervical NOx levels a parts per thousand currency sign99.9 mu mol/L (OR = 16.62), more than four lifetime male sexual partners (OR = 10.56), and age at first coitus of a parts per thousand currency sign15 years old (OR = 3.54). This combined model had a sensitivity of 86.49 %, a specificity of 90.74 %, a positive predictive value of 64.0 %, and a negative predictive value of 97.2 %.In the present sample, high-grade CIN associated with decreased cervical NOx levels. Thus, along with some clinical variables, cervical NOx levels may be an additional marker of cervical dysplasia.
