随机方法(请说明由何人用什么方法产生随机序列):

由研究负责人使用SPSS Statistics 22.0生成随机种子,创建包含1-86个自然编号的随机数字变量,通过软件将序列随机分配为1(试验组)、2(对照组)两组。

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

The research leader used SPSS Statistics 22.0 to generate random seeds and created random number variables containing 1-86 natural numbers. The sequences were randomly assigned into two groups, 1 (experimental group) and 2 (control group), using software.
