盲法:

由与本试验执行数据管理统计分析无关的统计学家,在计算机上用 SAS8.2 统计软件包,三组按照 1:1:1 的比例用分段随机化方法产生随机编码,所选择的 block长度和随机数初值等参数作为保密数据一起密封在盲底中。盲底保存在主要研究者所属的临床研究基地。除了随机化人员和药物编盲人员,其余人员(包括研究者、受试者、药品发放人员、结局评估者)试验期间均不知道分组情况。

Blinding:

The statisticians who are not related to the statistical analysis of data management performed in this experiment used SAS8.2 statistical software package on the computer to generate random codes by piecewise randomization method in a ratio of 1:1:1. The selected block length and initial value of random number were sealed in the blind base together as confidential data. The blind bottom is stored at the clinical research site to which the principal investigator belongs. Except for randomizers and drug programmers, the rest (including investigators, subjects, drug dispensers, and outcome evaluators) were not aware of the grouping status during the trial.
