Final answer:

The statement is true. Relative risk is used in cohort studies, while the odds ratio is used in case-control studies. Hence the statement is true.

Step-by-step explanation:

The statement is true.

Relative risk is indeed used with cohort studies, which involve a group of people who share the same experiences. In these studies, the incidence of a health-related event in an exposed group is divided by the incidence of the same event in a group that was not exposed to calculate the relative risk.

On the other hand, the odds ratio is used for case-control studies, which compare a group of subjects with a trait of interest (cases) to a group without the trait (controls). In these studies, researchers look for correlations between specific past behaviors and current status. The retrospective nature of case-control studies is their main weakness, as subjects' responses may be inaccurate.
