随机方法(请说明由何人用什么方法产生随机序列): |
由不参与本试验临床实施的统计单位使用SAS/SPSS软件按照1:1比例(试验组 20例,对照组 20例),模拟生成序列号为 1~40号包含受试者所接受处理的随机分配表,并依据随机分配表完成试验产品的编盲工作。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
A blinded random allocation table with serial numbers 1 to 40, containing the treatment assignment for each subject, was generated by the Statistical Unit not involved in the clinical trial procedures. Using SAS/SPSS software, the randomization was performed in a 1:1 ratio (20 cases in the experimental group and 20 cases in the control group). The blinding of the trial products was then completed according to this random allocation table. |
