This study evaluates the effectiveness of PAX1 methylation (PAX1m) analysis in identifying precancerous or cancerous lesions in cervical samples from Chinese women positive for non-16/18 hrHPV strains.  \nMethods Between February 2022 and March 2023, 281 cervical samples from non-16/18 hrHPV-positive women underwent cytological examination and PAX1m analysis. The study assessed the statistical relationship between PAX1m levels and the presence of cervical lesions, comparing the diagnostic performance of PAX1m to conventional cytology. Results A significant association was found between PAX1 methylation levels and the risk of CIN2 +and  \nCIN3 + lesions, with 47 instances of CIN2 +detected. Odds ratios (ORs) for moderate and high PAX1m levels were  \n8.86 (95% CI: 2 .24–42. 17) and 166.32 (95% CI: 47 .09-784. 97), respectively. The area under the ROC curve for PAX1min identifying CIN2 + lesions was 0.948 (95% CI: 0 .895–0. 99) . PAX1m demonstrated similar sensitivity and negative predictive value (NPV) to cytology but reduced the col poscopy referral rate from 47. 7% with cytology alone to 25. 6% with PAX1m, showing superior specificity and positive predictive value across age groups.  \nConclusions PAX1 methylation is a strong indicator of CIN2 +and CIN3 + risk, offering diagnostic performance comparable to cytology with the added benefit of reduced unnecessary col poscopy referrals. These findings support the use of PAX1m analysis as a reliable tool for triaging non-16/18 hrHPV-positive women in outpatient settings.
