Cohort study
What it is
A cohort study examines outcomes in a defined group, often comparing people with different exposures.
What it does
It can describe how outcomes vary with exposure over time.
Research context and ingredient forms
In an observational cohort, exposure is not assigned randomly, so differences between groups can complicate causal interpretation.
Using this information
An association between a food and an outcome should be read with the measured confounders, follow-up, and dietary measurement method in mind.
