随机方法(请说明由何人用什么方法产生随机序列): |
由独立于本试验的生物统计师,在计算机上通过SAS 9.4统计软件采用分层区组随机分组方法、基于系统生成的随机种子数(由统计师盲选产生)和区组长度编制随机化程序,生成随机号和分组信息,产生随机的种子数以及随机结果作为盲底保存。预先生成516个连续编号(001-516)的随机分配序列,每个编号对应唯一的治疗分配(干预组或对照组,比例为1:1),并打印密封于信封之中,每个信封内包含该编号对应的分组信息。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
A biostatistician independent of this trial used SAS 9.4 statistical software on a computer to develop a randomization program via the stratified block randomization method, based on a system-generated random seed (selected blindly by the biostatistician) and block length. This program generated random numbers and group assignment information, with the random seed and randomization results stored as the blind bottom (unblinded master randomization list). A random allocation sequence of 516 consecutive numbers (001–516) was generated in advance, with each number corresponding to a unique treatment assignment (intervention group or control group, in a 1:1 ratio). These sequences were printed, sealed in envelopes, and each envelope contained the group assignment information corresponding to the numbered sequence. |
