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):

本研究承诺在研究成果(主要结果论文)正式发表后12个月内,向科学界共享去标识化后的个体参与者数据(IPD),共享方式为通过公开的数据存储库(Figshare) 提供数据集下载链接翻译

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

This study commits to sharing de-identified individual participant data (IPD) with the scientific community within 12 months upon the formal publication of the primary results manuscript. The data will be shared via a public data repository (Figshare) by providing a dataset download link.

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:

临床数据: 使用标准化的病例报告表(CRF)收集,包括人口统计学资料(性别、年龄、身高、体重)、病史、手术记录、随访期间的体重、血糖、血脂、生命体征、实验室检查结果等。 样本数据: 分别收集术前基线、术后3月、术后6月、术后12月的血液及粪便标本,建立严格的样本追踪链(Chain of Custody),确保从采集、处理、储存到检测的全过程可追溯。所有样本使用唯一研究编号标识。 翻译

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

Clinical data will be collected using standardized Case Report Forms (CRFs), encompassing demographic information (sex, age, height, weight), medical history, surgical records, and follow-up data including body weight, blood glucose, blood lipids, vital signs, and laboratory test results. Biospecimen data involve the collection of blood and stool samples at the following time points: preoperative baseline, and at 3, 6, and 12 months postoperatively. A strict Chain of Custody will be established to ensure full traceability throughout the entire process from collection, processing, and storage to final analysis. All samples will be labeled with a unique study identifier.
