本研究数据采集严格遵循《医学研究数据管理规范》及伦理审批要求,采用标准化流程执行。临床结局指标(如 CRS-R、GCS 评分)和诱发电位结果(SEP,BAEP,MMN)由经过统一培训的独立研究者双人同步记录,客观脑功能数据(EEG、fNIRS、fMRI、DTI,MRS)通过校准后的仪器采集并自动存储原始文件。数据录入采用加密电子数据采集系统(EDC),设置逻辑校验规则,录入后由专人进行双人核对,确保数据准确性与完整性。 数据存储于符合国家信息安全等级保护要求的专用服务器,实行权限分级管理,仅授权人员可访问。研究期间定期进行数据备份与完整性检查,数据库锁定后仅可通过授权流程修改。数据保存期限为研究结束后 10 年,遵循隐私保护相关法规。

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

This study strictly complied with the Specifications for Medical Research Data Management and ethical approval requirements, and all data collection procedures were implemented in a standardized manner. Clinical outcome indicators (such as CRS?R and GCS scores) and evoked potential results (SEP, BAEP, MMN) were synchronously recorded by two independent and uniformly trained researchers. Objective brain functional data, including EEG, fNIRS, fMRI, DTI, and MRS, were collected using calibrated instruments and stored automatically as original files.Data entry was performed through an encrypted electronic data capture (EDC) system with built?in logical validation rules. Double data checking was conducted by dedicated personnel after entry to ensure data accuracy and completeness. All research data were stored on a dedicated server that meets national information security level protection standards with hierarchical access control, and only authorized personnel are permitted to access the data. Regular data backup and integrity verification were performed throughout the study. After database locking, any data modification required official authorization. In accordance with relevant privacy protection regulations, research data will be retained for 10 years upon study completion.
