PUB-540 Topic 4 DQ 2

Describe the characteristics and design of a cohort study. Based on a disease or health condition identified from the "2020 LHI Topics" on the Healthy People 2020 website, or an article from the GCU library, discuss a real example of a cohort study (include the link to the article in your post to the forum). Include the participants, exposures or treatment groups, timeframe, and outcomes that were measured. Why is a cohort study described as an "observational" study rather than an "experimental" study design?
