摘要
目的介绍利用Stata软件实现临床试验随机化分组的方法。方法通过举例展示如何应用Stata软件实现各类临床试验随机化分组。结果利用Stata分别实现了简单随机化分组、分层随机化分组、区组随机化分组以及确定处理因素的随机化。结论 Stata可轻松实现临床试验中的随机化分组要求。
Objective To introduce how to use Stata software to implement the randomization of clinical trials. Methods Some examples were taken to describe bow to implement the randomization of each kind of clinical trials. Re- sults Stata implemented its required functions, such as simple randomization, stratified randomization, block randomiza- tion and the randomization of group treatment. Conclusion Stata can easily implement the randomization of clinical trials.
