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):

在研究成果于学术期刊发表后 6 个月内开始提供。 方式: 本研究中去标识化后的个体参与者数据(IPD)将被共享。数据将在合理要求下,为达成预设的研究目标,提供给经过批准的研究人员。申请者需提供详细的研究计划,并签署数据使用协议。数据将通过以下网络平台提供: 网络平台名称: Figshare 网址: https://figshare.com/

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

Deidentified individual participant data (IPD) from this study will be made available within 6 months after the research results are published in academic journals. Method: Deidentified IPD from this research will be shared. The data will be provided to approved researchers upon reasonable request to achieve predefined research objectives. Applicants must submit a detailed research proposal and sign a data use agreement. The data will be accessible via the following online platform: Platform Name: Figshare Website: https://figshare.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:

1.病例记录表 (CRF): 基于研究方案,我们设计了一份标准化的数据收集表格,用于从医院信息管理系统(HIS)和电子病历(EMR)中回顾性提取所需变量。 2.电子采集和管理系统: 提取的数据由两名研究人员独立录入到 Microsoft Excel 表格中,并进行交叉比对以确保准确性。最终数据由研究负责人使用 IBM SPSS Statistics (版本 26.0) 进行统一管理和统计分析。

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

1.Case Report Form (CRF): Based on the study protocol, we designed a standardized data collection form to retrospectively extract required variables from the Hospital Information System (HIS) and Electronic Medical Records (EMR). 2.Electronic Collection and Management System: The extracted data were independently entered into Microsoft Excel spreadsheets by two researchers and cross-verified to ensure accuracy. The final dataset was uniformly managed and statistically analyzed by the principal investigator using IBM SPSS Statistics (Version 26.0).
