随机方法(请说明由何人用什么方法产生随机序列):

采用双中心独立区组随机化。随机数列应由与本项目无直接关联的独立统计师,使用专业的随机化软件SAS来产生。独立统计师需按1:1的分配比例,设置一个对临床研究者保密的区组长度,通过软件生成随机序列,生成的随机分组结果按顺序装入按顺序编号的不透光信封以实现隐蔽分组。

Randomization Procedure (please state who generates the random number sequence and by what method):

A dual-center independent block randomization will be adopted. The random sequence shall be generated by an independent statistician not directly involved in this project using professional randomization software (SAS). The statistician will set a block size that is concealed from clinical investigators, generate the random allocation sequence in a 1:1 ratio, and sequentially place the randomization results in sequentially numbered, opaque, sealed envelopes to ensure allocation concealment.

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):

本研究计划在主要研究结果论文发表后6个月起,通过中国临床试验注册中心(ChiCTR)的临床试验原始数据公共管理平台——临床研究数据管理平台(ResMan,网址:http://www.medresman.org),向公众公开本研究的去标识化个体受试者原始数据。数据共享将遵守该平台的相关政策与流程。

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

This study plans to make the de-identified individual participant data publicly available through the clinical research data management platform (ResMan, URL: http://www.medresman.org), which is the primary data public management platform of the Chinese Clinical Trial Registry (ChiCTR). Data sharing will commence starting 6 months after the publication of the main research findings and will comply with the relevant policies and procedures of the platform.

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:

本研究采用结构化的病例记录表进行数据采集。所有数据将通过基于互联网的临床研究数据管理平台进行电子化录入与管理。我们使用中国临床试验注册中心推荐的ResMan系统作为电子数据采集系统,该系统网址为 http://www.medresman.org。

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

This study employs a structured case report form (CRF) for data collection. All data will be electronically entered and managed via an internet-based clinical research data management platform. We utilize the ResMan system, an electronic data capture (EDC) system recommended by the Chinese Clinical Trial Registry (ChiCTR), accessible at http://www.medresman.org.
