随机方法(请说明由何人用什么方法产生随机序列):

本试验采用随机的方法进行受试者的入组分配。受试者随机号由随机化单位项目独立非盲统计人员基于方案,采用SAS®9.4或更高版本,按照区组随机的方法产生受试者随机盲底,盲底的内容包括有编号、治疗分组以及区组。

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

A randomization method was used for subject allocation in this trial. The randomization numbers for subjects were generated by an independent unblinded statistician from the randomization unit based on the protocol, using SAS® 9.4 or a higher version with a block randomization method to produce the subject randomization list. The randomization list included assignment numbers, treatment groups, and blocks.
