[交流] 临床研究limitation的几种写法

limitation的几种写法
原则:有一些致命性的limitation不要提
一般流程:存在什么问题?没有解决这个问题的原因?以后要怎么办(也可以不写)?
第一句通常会说This study is not without limitations./ Our study has limitations./Our study had several major limitations.

1.Sample size较小
2.伦理问题:Owing to an ethical reason, we cann't/can only do sth
3.Selection bias选择偏倚的问题: Relatively less disabled patients were recruited for better compliance to treatment and imaging follow-up
This study was performed in a selected population with…. Which may limit the generalization of the findings.
4.是否是在一个selected population: 例如1.Our study excluded patients with prior CABG, and thus the utility of FFR-CT in this population remains unknown. Future studies will be required to determine its diagnostic performance in this population.
5.其他的一些不足:根据每个study的特点来定
