All subjects underwent HPV-DNA testing, cytological examination, colposcopy, and <jats:italic>PAX1<\/jats:italic> gene methylation detection, with results analyzed in conjunction with histopathological evaluations. HPV-DNA detection was performed using fluorescence quantitative PCR methodology capable of identifying 17 high-risk HPV genotypes. Cytological examination results were classified according to the International Society of Cytology standards. <jats:italic>PAX1<\/jats:italic> gene methylation detection employed fluorescence quantitative PCR technology with ACTB as the internal reference gene, determining methylation levels through calculation of \u0394CT values. Statistical analyses included ROC curve assessment of diagnostic performance, with intergroup comparisons conducted using one-way analysis of variance and Pearson\u2019s chi-squared test.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The results demonstrated that PAX1 gene methylation detection showed significantly better diagnostic performance compared to cytological examination for the detection of CIN2+ and CIN3+ lesions. The AUC values for <jats:italic>PAX1<\/jats:italic> gene methylation detection in diagnosing CIN2+and CIN3+ were 0.934 (95% confidence interval [CI]: 0.916\u20130.948) with sensitivity of 93.49% and specificity of 93.24%and0.875 (95% confidence interval [CI]: 0.853\u20130.895)with sensitivity of 95.31% and specificity of 79.77%. Among non-16\/18 HR-HPV(in women positive for high-risk HPV types other than 16\/18) positive patients, <jats:italic>PAX1<\/jats:italic> gene methylation detection demonstrated higher sensitivity and specificity than cytological examination, enabling more accurate identification of patients requiring further intervention and reducing unnecessary colposcopy referrals. Furthermore, in HR-HPV positive patients with cytology results \u2264ASCUS, <jats:italic>PAX1<\/jats:italic> gene methylation detection significantly decreased colposcopy referral rates (22.29%), thus
