cohort studies

What Are the Advantages of Cohort Studies?


Temporal Relationship: Cohort studies establish a clear temporal sequence between exposure and outcome, which is crucial for inferring causality.
Multiple Outcomes: They allow for the study of multiple outcomes from a single exposure.
Direct Measure of Risk: Incidence rates can be directly calculated, providing a measure of risk associated with the exposure.
Minimized Bias: Prospective cohort studies minimize recall bias since data on exposure is collected before the outcome occurs.
