数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

本研究采用标准化病例记录表(Case Record Form, CRF)进行数据采集,内容涵盖患者入组筛选信息、围妊娠期临床病程、AQP4-IgG 滴度检测结果、EDSS 评分、治疗方案、妊娠结局及随访数据等;同时依托电子数据采集与管理系统(Electronic Data Capture, EDC)完成数据录入、核查、锁定与存储,严格遵循临床试验质量管理规范(GCP)要求,确保数据的真实性、完整性、可追溯性与保密性。

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

Data collection and management will be conducted in compliance with Good Clinical Practice (GCP) guidelines. A standardized Case Record Form (CRF) will be used to collect data including patient screening information, peri-pregnancy clinical course, AQP4-IgG titer results, EDSS scores, treatment regimens, pregnancy outcomes and follow-up data. An Electronic Data Capture (EDC) system will be applied for data entry, verification, locking and storage to ensure the authenticity, completeness, traceability and confidentiality of all study data.
