Introduction

Methodologically, the cohort study best approximates the randomized controlled trial (RCT), it samples on exposure and follows study participants through time for the development of the outcome of interest. As such, the cohort study is considered one of the leading observational epidemiological study designs. The following exercise will show you the key features of the cohort design.

Good luck and have fun!
