A. they take less time and are less costly. B. they can utilize a more representative population. C. it is easier to obtain controls that are not exposed to the suspected factor. D. they permit direct estimation of risk of disease in those exposed to thesuspected factor. E. they can be done on a double-blind basis.

A major advantage of cohort studies over case-control studies with respect to the role of a suspected factor in the etiology of a disease is that they permit direct estimation of risk of disease in those exposed to the suspected factor.

Explanation:

The major advantage of cohort studies over case control studies are :

1.It is suited for rare exposures  since starting with exposure status.

2.Allows for studying several outcomes.

3.Exposure status easier to ascertain  since starting point of the study.

4.Allows computation of risk and rates.

5.Allows studying natural history of disease, easier to show that cause precedes effect.

6.Easiness to find a reference group , usually not difficult to identify an unexposed population.

7.Sample size  taken is large.

8.Concept s are easy to understand.
