The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url):

Within 6 months of publication, the raw data will be made publicly available through ResMan (http://www.medresman.org.cn/login.aspx). Data usage is subject to prior authorization, which can be obtained by contacting the researcher at zhouxiaoyang_1990@163.com.

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:

研究开展前预先制定一张临床病例报告表,设计并制定好数据管理制度、流程与实施计划,进一步制定相应详细的标准操作规程(SOP),作为具体实施的依据。本研究所有临床数据均由一位独立的研究人员按照事先制定的研究者手册及SOP进行采集,该人员对研究方案不知情。所有超声心动图的操作及数据记录均由另一位研究人员独立完成,该人员同样对研究方案不知情。由以上两位研究人员应用EpiData软件进行数据的双录入。在此期间,项目负责人对数据进行实时监查,保证遵循研究方案进行,研究记录及报告数据及时填写,及数据采集的准确性和完整性。

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

Before conducting the research, prepare a clinical case report form in advance, design and develop a data management system, process, and implementation plan, and further develop corresponding detailed standard operating procedures (SOP) as the basis for specific implementation. All clinical data in this study were collected by an independent researcher in accordance with a pre established investigator manual and SOP, who was unaware of the study protocol. All operations and data recording of echocardiography were independently completed by another researcher who was also unaware of the research protocol. The above two researchers applied EpiData software for dual data entry. During this period, the project leader conducted real-time monitoring of the data to ensure compliance with the research protocol, timely completion of research records and report data, and accuracy and completeness of data collection.
