Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Case Report Form (CRF): Forms designed according to the study protocol to capture core research data across all visits; completed by GCP-trained personnel following standardized procedures. Hard copies are securely stored and locked in the filing cabinet of Clinic 312, Comprehensive Oral Medical Department, Wangfujing Hospital, with regular audits.Management: An electronic database corresponding to the CRF is established, into which data from paper forms are entered within 24 hours, annotated only with subjects' unique research identifiers. Files are stored on the research team's dedicated computer, with access restricted to authorized personnel, and are regularly backed up. Upon completion of all follow-ups, data are verified and locked; any modifications require a formal written application and detailed documentation.
