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:

研究将通过纸质版病例报告表(CRF)收集所有入组患者的接受维生素K2治疗的信息、临床结局和患者特征信息;将通过纸质或电子问卷收集患者报告结局。根据中国相关法规规定,可以在观察性临床研究中使用患者报告的结局(Patient-Reported Outcomes, PROs)(中国NMPA,2021)。所有数据将通过Epidata双人录入后进行妥善保存。

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

The study will collect information on Vitamin K2 treatment received, clinical outcomes, and patient characteristics for all enrolled patients using ??paper-based Case Report Forms (CRFs)??. ??Patient-Reported Outcomes (PROs)?? will be collected via paper-based or electronic questionnaires. According to relevant Chinese regulations, the use of Patient-Reported Outcomes (PROs) is permitted in observational clinical studies (China NMPA, 2021). All data will be entered into the database using ??double-data entry in EpiData?? and subsequently ??appropriately preserved??.
