随机方法(请说明由何人用什么方法产生随机序列):

由研究者使用Excel制作出随机数表格,随机分配出35个1和35个2,以1代表对照组,2代表试验组,使两组数量均衡。而后根据受试者编号对照随机数表格进行分组。

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

The researchers used Excel to produce random number tables, randomly assigned 35 1 and 35 2, 1 represented the control group, 2 represented the experimental group, and the number of two groups was balanced.Then, the random number table is grouped according to the number of subjects.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

不公开/Private

盲法:

单盲(对评价者盲)。设置单独评价者,评价者不知道也不允许询问受试者信息,故评价者将不知道受试者分组。

Blinding:

This trial is a single-blind trial. There will be a individual evaluator who does not know and does not allow to inquiry the information of the patients. So evaluator does not know the treatment allocation of any patient.

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):

试验结束后6个月内公开,方式为邮件获取。

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

Within 6 months after the trial complete, it is open for mail acquisition.

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 2.电子病例记录表

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

1.Case Record Form 2.Digital Case Record Form
