随机方法(请说明由何人用什么方法产生随机序列):

采用系统生成一个种子数,设置样本量和区组长度,由 PROC PLAN 过程,生成试验所需的随机数字表,导入随机系统。由研究者登录中央随机系统,录入受试者信息,根据随机系统分组,将受试者随机分配到试验组或对照组。

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

Use the system to generate a seed number, set the sample size and block length, generate the random number table required for the experiment by the PROC PLAN process, and import it into the random system. The researcher logs into the central random system, enters the subject information, and randomly assigns the subjects to the test group or the control group according to the random system grouping.
