随机方法(请说明由何人用什么方法产生随机序列):

参研医生使用由根据入选标准和排除标准在随机化程序进行随机化分组,并且生成随机化序列。随机将通过由四川知天科技公司一个24小时密码保护、基于互联网随机化系统的微信内置程序登记患者并获取予以该患者应服用的药物。随机序列将会使用一种简单的算法实现对主要预后因素的平衡,随机将根据患者随机化发病时长(≥24小时vs <24小时)、年龄(≥65岁vs <65岁)和MARADP水平(≥55% vs <55%)进行分层。

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

The doctors participating in the study use a randomization procedure based on inclusion and exclusion criteria to conduct random grouping and generate a randomization sequence.Patients will be randomized using a 24-hour password-protected, web-based randomization system integrated with WeChat, provided by Sichuan Zhitian Technologies Co., Ltd. The program embedded in WeChat will register patients and obtain the medication that should be taken by the patient. The randomization sequence will be stratified using a simple algorithm to balance for key prognostic factors: duration from disease onset to randomization (>=24 hours vs <24 hours), age (>=65 years vs <65 years), and MARADP level (>=55% vs <55%).

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):

当研究的主要文章发表24个月后,如果需要本研究的原始数据,需要提交申请表到主要研究单位,由研究负责人审批签字同意后,给予其原始数据。

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

When the main article of the study is published 24 months later, if the original data of this study is required, an application form needs to be submitted to the main research unit and PI.

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:

本研究将通过互联网系统来协助本研究的管理。纸质版的病案报告表(CRFs)将和研究操作手册一起提供给研究中心,这些资料包含了每个数据点的定义,可作为医院完成电子数据库的指南,保证数据收集的准确性与一致性。 将通过互联网管理系统(名称:EDC系统,网址:http://z1.simrm.com:18093/ )来实现所有的数据录入。通过基于互联网的数据管理系统,可以进行实时数据录入、对合理范围之外的数值产生质疑,并进行一致性检查。所有研究相关的表格和档案将由研究中心保存在上锁的文件柜里。

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

This study will assist the management of this study through the Internet system. Paper version of the Case Report Forms (CRFs) will be provided to the research center along with the study operating manual. These documents contain the definition of each data point and can be used as a guide for the hospital to complete the electronic database (EDC, http://z1.simrm.com:18093/) to ensure the accuracy and consistency of data collection. All data entry will be accomplished through an internet management system. The Internet-based data management system enables real-time data entry, questioning of values outside reasonable ranges, and consistency checks.All research related forms and files will be kept by the research center in a locked filing cabinet.
