随机方法(请说明由何人用什么方法产生随机序列):

使用中央随机系统,受试者签署知情同意书并完成基线评估后,研究者访问系统获取分组信息,确保在入组前无法预知分组情况。

Randomization Procedure (please state who generates the random number sequence and by what method):

Using a central randomization system, after participants sign the informed consent form and complete the baseline assessment, researchers access the system to obtain group assignment information, ensuring that the group allocation cannot be predicted before enrollment.

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:

数据采集:由研究者将数据及时、完整、清晰记录于病例报告表中。数据管理:统计人员将病例报告表中记录数据誊写整理于电子Excel表中,并进行统计分析。电子记录+纸质材料留档。

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

Data collection: The researcher records the data in the case report form in a timely, complete and clear manner. Data management: Statisticians transcribe and organize the recorded data in the case report form in an electronic Excel table and perform statistical analysis. Electronic records + paper materials to keep files.
