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):

本研究在试验结束后,计划于 2026年12月31日 前通过 Figshare 公开共享匿名化的原始数据。 数据将包括:研究方案、统计分析计划、去标识化的个体参与者数据(IPD)等。

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

Upon completion of the trial, this study plans to publicly share anonymized raw data via Figshare by December 31, 2026. The shared data will include the study protocol, statistical analysis plan, de-identified individual participant data (IPD), among other relevant documents.

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:

本研究采用手麻系统进行数据采集,病例记录表(CRF)已集成至该系统中,确保数据采集的标准化与实时质控。所有数据在录入后进行逻辑核查与匿名化处理,确保数据质量与隐私安全。

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

This study utilized an anesthesia information management system (AIMS) for data collection. The Case Report Form (CRF) was integrated into this system to ensure standardized data capture and real-time quality control. All data underwent logical checks and anonymization after entry to guarantee data quality and privacy security.
