随机方法(请说明由何人用什么方法产生随机序列):

本项目采用分层区组随机化方法纳入短病程(≤6年)患者153人和长病程(>6年)患者198人,共计351名2型糖尿病患者。由专业统计人员通过计算机随机数字表法对每个招募点的研究对象进行随机分组,分层因素为肥胖程度(24-27.9kg/m2、28-32.4kg/m2和32.5-45kg/m2),区组大小为3或6,按照 1:1:1 入组。随机分配入组将由与本试验执行数据管理及统计分析无关的统计人员完成。

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

Using a stratified block randomization approach, this study plans to enroll 351 individuals with type 2 diabetes in total, including 153 participants with a short diabetes duration (<=6 years) and 198 with a long diabetes duration (>6 years). A statistician not involved in the management and analysis of study data will use a computer-generated random number table for each recruitment site. The stratification factor is severity of obesity (24-27.9kg/m2, 28-32.4kg/m2, and 32.5-45kg/m2). The block sizes used are 3 and 6. Enrolled participants will be randomly allocated to each of the three arms in a 1:1:1 ratio.
