随机方法(请说明由何人用什么方法产生随机序列):

本研究采用分层区组随机方案。根据中心进行分层,再由统计人员选取合适区组长度(区组大小为4),组间分配比例为1:1,利用SAS软件给定代码,产生随机序列,列出随机编码表。

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

n this study, stratified blocked randomized scheme will be adopted. Stratification will be done according to the centers, then the statistician will select the appropriate length of zonal group (zonal group size of 4), with a 1:1 allocation ratio between the groups. Participants will be randomly assigned to one of groups using SAS statistical software for random number generation.
