approaches to group-based analytical studies Correct Answers
-cohort method: examines individuals who share a particular
characteristic; prospective or retrospective
-case-control: compares groups with disease to group without;
commonly retrospective
-cross-sectional: group is randomly selected, compares disease
and no disease at a point in time; looks for associations of
measurable variables (s) and the disease
