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:

本研究为回顾性队列研究,研究数据来源于医院电子病历系统、影像存档与传输系统(PACS)及门诊随访记录。收集内容包括患者一般资料、术前及末次随访负重位X线影像学参数、临床评分及术后并发症情况。所有影像学参数由两名独立观察者采用手工测量方式完成。 所有数据进行去标识化处理后录入电子数据库(Excel/SPSS),由专人负责管理。数据采用双人核对方式确保准确性,并设置密码保护,仅限研究成员访问。研究数据定期备份,确保信息安全。

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

Clinical and radiographic data were retrospectively collected from the hospital electronic medical record system and the Picture Archiving and Communication System (PACS). Collected variables included demographic information, preoperative and final follow-up weight-bearing radiographic parameters, clinical scores, and postoperative complications. All radiographic measurements were performed manually by two independent observers.All data were anonymized prior to analysis and entered into a secured electronic database. Data accuracy was verified through double-checking procedures. Access to the database was restricted to authorized study investigators.
