随机方法(请说明由何人用什么方法产生随机序列):

本试验采用区组随机化方法将受试按1:1比例随机分配至试验组和对照组。由独立的非盲统计师以SAS软件(9.4)产生随机号以及随机号所对应治疗组别。受试者随机由IWRS系统完成,筛选合格以后的受试者将按照入组先后顺序获得一个随机号。药物编号会由IWRS系统根据随机分组情况进行分配。

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

In this study, the subjects are randomly assigned to the experimental group and the control group in a 1:1 ratio by block randomization method. Random numbers and treatment groups corresponding to random numbers were generated by an independent, non-blind statistician using SAS software (9.4). Subjects were randomized by the IWRS system, and qualified subjects were assigned a random number in the order of enrollment. Drug numbers are assigned by the IWRS system based on randomization.

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:

受试者、研究者以及数据管理、统计分析等项目相关人员均不知晓治疗药物的分配情况
