Question

A strength of the cohort study compared to the case-control study is: A. Information on disease is generally of high quality B. Confounding cannot occur C. Multiple outcomes can be evaluated from a single exposure D. Confounding is easily measured E. None of the above

Answer 1

Answer: C. Multiple outcomes can be evaluated from a single exposure

Explanation:

Cohort studies continue with a disease-free group of people (a cohort). The cohort's people are divided by whether or not they're prone to a possible cause of illness. The entire cohort is monitored over time to see how the emergence of new cases of the disease (or other outcome) varies with and without exposure between the classes.

In a case-control analysis too, the same disease can be studied. A case-control research starts with the collection of cases including people with a disease and the tests which includes people without the disease. The controls would represent people who would have been cases of research had the disease formed (population at risk).

The advantage of Cohort studies over a case-control study involves that one can determine variety of outcomes/diseases caused by one exposure for example,  lung disease, heart disease, and smoking-caused renal disease.

Hence, the correct option is C." Multiple outcomes can be evaluated from a single exposure".
