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

The raw data are planned to be made publicly available on the ResMan raw data–sharing platform (IPD sharing platform) of the Chinese Clinical Trial Registry in December 2027 and can be accessed at http://www.medresman.org.cn.

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:

本研究的所有数据将使用根据方案专门设计的纸质病例记录表(CRF)进行采集。研究护士在每次访视后,需及时、完整、准确、规范地填写CRF,所有修改必须签注姓名和日期。数据录入阶段,由两名项目秘书进行双人独立录入到电子数据库中,随后进行一致性比对与人工逻辑核查。所有发现的数据疑问(如缺失、异常或逻辑矛盾)将由数据管理员生成纸质数据疑问表,返回给原始填写者(研究护士)进行核查、说明与修正,修正过程需经主要研究者审核,所有疑问表均需归档保存。在主要指标采集完成且所有疑问解决后,最终数据库将进行冻结与锁定,锁定后的数据方用于统计分析。整个数据管理过程将严格遵循GCP原则,并通过上述明确分工与多重核对机制确保数据的真实性、准确性、完整性和可溯源性。

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

All data in this study will be collected using paper Case Report Forms (CRFs) that are specifically designed according to the protocol. Research nurses are required to fill out the CRFs promptly, completely, accurately, and in accordance with standards after each visit, with all modifications signed with their name and dated. During the data entry phase, two project secretaries will independently enter the data into an electronic database, followed by consistency comparison and manual logical verification. Any identified data queries (such as missing, abnormal, or logically inconsistent data) will be generated into paper data query forms by the data manager and returned to the original data entry personnel (research nurses) for verification, clarification, and correction. The correction process must be reviewed by the principal investigator, and all query forms must be archived. Once the collection of primary endpoints is complete and all queries have been resolved, the final database will be frozen and locked, with only the locked data used for statistical analysis. The entire data management process will strictly adhere to GCP principles, ensuring the authenticity, accuracy, completeness, and traceability of the data through clear division of responsibilities and a multi-check mechanism.
