随机方法(请说明由何人用什么方法产生随机序列):

试验采用相邻顺序入组的患者进行编号,进行随机分组。随机分配编码由统计学专业人员采用SAS9.12软件在计算机上编程产生。按照试验和对照组1:1:1:1比例,产生304例受试者的随机分组安排,即列出流水号001-304所对应的治疗分配,且流水号与受试者编号对应。

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

The random assignment codes are generated by statistical professionals using SAS 9.12 software. According to the ratio of 1:1:1:1 for the intervention and control groups, a randomized grouping arrangement is set up for 304 subjects. The serial number 001-304 was listed and corresponds to each participant.
