这学期参加了一个journal club “tell me something I don’t know about cancer”，获益匪浅。特别是通过交流学习，是我这种小白对epidemiology和cancer有了更深的认识。

通过对每次journal club上文章的critisize, 不仅培养了批判性思维，还同时对该领域的文章结构有了很清晰的认识。很好的东西，必须记下来，好记性不如烂笔头嘛。写文章的时候对照这些问题，就会删了很多bug呢。

同时，主持journal club的Ofure还给我们推荐了 a Series on Evaluation of Scientific Publications ，该书的第一章Critical Appraisal of Scientific Articles 就是告诉我们如何严谨的写作科研文章。经常读读是大有裨益的，该书共21章，每章针对不同的方面都会有专题，特别专业。

以下是在写流行病学方面文章需要的注意事项，从三个方面来总结：

Introduction

• Does the title adequately reflect the work content? Is it unbiased?

• Is it relevant to the topic selected and does it show the objectives or aims of the research article?
• Is the research question or hypothesis clear?
