Enrolled subjects were randomly divided into two groups. Methylation test + colposcopic biopsy was performed in the conventional group, and clinical follow-up was performed according to the methylation results; in the experimental group, methylation test + colposcopic biopsy +OITS was performed, and clinical follow-up was performed according to the methylation results and OITS results. To verify the effectiveness of methylation tests and OITS in screening for CIN2+, whether they can reduce missed diagnosis of CIN2+, whether they can flag excessive colposcopic procedures, and the value of clinical follow-up for cervical lesions.'}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '18 Years', 'samplingMethod': 'PROBABILITY_SAMPLE', 'studyPopulation': 'There are 30 multi-center units in the country, and each center competes to enter the group.
