随机方法(请说明由何人用什么方法产生随机序列):

研究人员设计区组随机化统计方法 实验组和对照组随机分成两组,设计区组长度为4,组内设置四个研究对象,其排列有六种方式。(1. AABB, 2. ABAB, 3. ABBA, 4. BAAB, 5. BABA, 6. BBAA)。通过EXCEL随机产生一组数据(0~9),只选择1-6的数据10个,按顺序选取区别,共40个数据。将纳入标准的患者按序纳入A、B组,实验组和对照组均等分为数量相等的两组。

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

the statistical approach of block randomization designed by research worker. The experimental group and control group were randomly divided into two groups.the design length of block is four,every block includes four study objects,its arrangement is six ways (1. AABB, 2. ABAB, 3. ABBA, 4. BAAB, 5. BABA, 6. BBA
