是否共享原始数据:

IPD sharing

是Yes

共享原始数据的方式(说明:请填入公开原始数据日期和方式,如采用网络平台,需填该网络平台名称和网址):

研究结束后 12 个月,主要研究人员可以提出合理请求获取数据,但此类请求需付费。此政策符合提供研究数据以供进一步分析和验证的常见做法,同时承认研究团队投入的时间和资源。

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

After the conclusion of the research at the 12-month mark, the data may be accessible upon reasonable request to the principal investigator, with the understanding that such requests are subject to a fee. This policy aligns with the common practice of making research data available for further analysis and validation while acknowledging the time and resources invested by the research team.

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:

实验室指标由HIS系统中直接提取,手术相关指标由参与手术的一名指定医生收集并记录,随访相关指标由随访小组成员收集并记录,所有变量按照上述分类建立专门的Epidata文件,生成每名患者的专属病例报告表,最后导出为Excel格式管理。所有数据由专人汇总并保存,所有患者的隐私都确定得到保护。

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

Laboratory indicators were extracted directly from the HIS system, surgery-related indicators were collected and recorded by a designated physician involved in the surgery, follow-up-related indicators were collected and recorded by a member of the follow-up team, and all variables were categorized according to the above to create a dedicated Epidata file, generating an exclusive case report form for each patient, and finally exported to Excel format for management. All data were summarized and stored by a dedicated person, and the privacy of all patients was determined to be protected.
