随机方法(请说明由何人用什么方法产生随机序列):

本实验的研究者采?随机数表的?法,对符合纳?条件的样本进?随机选取。?先对所有符合纳?标准的样本进??然数列编码,然后使?SPSS软件产?随机数列,选择研究样本。受试者就诊顺序与随机数字进?匹配并完成分组。

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

The researchers of this experiment used the method of random number table to randomly select the samples that met the inclusion criteria. First, all the samples that met the inclusion standards were encoded with natural number sequences. Then, the SPSS software was used to generate a random number sequence to select the research samples. The order of the subjects' visits was matched with the random numbers and they were grouped accordingly.
