Assignment:

Which study design offers the best opportunity to control for confounding -- randomized clinical trial, cohort study, or case-control study? Explain your reasoning and make examples to prove your point. Suppose that in the study of pesticide use and breast cancer you wanted to evaluate the hypothesis that pesticide use varies by geographic area. Would you match on geographic area? Please, explain your answer. A principle of case-control studies is that controls should be selected independently of exposure status. Under what circumstances would matching violate this principle? What can be done about this type of violation?
