A quick look at the what is the meaning of recessive gene page of a biomedical journal or even at the health news section of a news website is enough to tell you that there are many different ways to conduct epidemiological research.

In this course, you will learn about the main epidemiological study designs, including cross-sectional and ecological studies, case-control and cohort studies, as well as the more complex nested case-control and case-cohort designs. The final module is dedicated to randomised controlled trials, which is often considered the optimal study design, especially in clinical research.

You will also develop the skills to identify strengths and thw of the various study designs. By the end of this course, you will be able to choose the most suitable study design considering the research question, the available time, and resources.
