随机方法(请说明由何人用什么方法产生随机序列):

随机分配编码由统计学专业人员采用 SAS 9.4 及以上版本软件在计算机上模拟产生,并采用牛皮信封进行分配 隐藏。随机化过程中所设定的区组长度、种子数和 SAS 程序将一同保存在随机化过程记录中,以保证该随机号编码具有可重现性。

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

The randomization allocation codes were generated by a statistical professional using SAS software (version 9.4 or higher) through computer simulation, and allocation concealment was performed using opaque envelopes. The block length, seed number, and SAS program used in the randomization process were all documented and preserved in the randomization procedure records to ensure the reproducibility of the randomization codes
