Cohort Studies
Captions available
The idea
A cohort study follows a group over time to see what outcomes develop, comparing those with an exposure against those without.
In practice
Two groups followed forward, differing in one exposure.
Where people slip
A cohort study observes an exposure it did not assign, so any difference between the groups may be doing the work.
