Cohort studies have a control group where a group of people with something in common (a cohort) are followed. This group is compared to another group with similar characteristics/circumstances, with the exception of the factor being investigated.

Cohort studies are observational and not as reliable as randomized controlled studies, since the two groups may differ in ways other than in the variable under study.
