Understanding the differences among the types of epidemiological study designs is important for translating the results to public health practice. Your Instructor will provide three articles that illustrate different epidemiological study designs: case-control, cohort, and randomized controlled trial. 
For this Discussion, you will identify and analyze epidemiological research studies through the provided research articles. In addition, you will consider the ethical principles that are unique to each type of study design.
To prepare:
Select one of the articles provided by your instructor and closely review the methods section.

Select one of the three provided articles to summarize the study in your own words, identify the study design it uses, and discuss what features it has that identify it as the particular type of study design.   
In your summaries, please do not just copy the abstract or parts of the article. For the study you selected, be sure to include information on who the participants are, which data collection methods were used, and how the exposure and outcome variables were measured. Finally, explore the ethics involved in the study. What are the costs and benefits to the participants in the study?
