3. It assesses causation well for all exposures.
4. It is beneficial in studying rare outcomes.
5. It clearly defines temporality of the exposure being measured.

27. Select the best description of an ecological/correlational study design.

1. Examines relationships between a risk factor and a disease outcome at the population level
2. Creates a “snapshot” of an existing disease and factors that may be associated
3. Used to determine potential exposures in relation to a disease outcome; a group with the disease is recruited and compared to an equivalent group without disease
