Abstract
There are four stages in the execution of an analytic study. The first is the statement of a research hypothesis,i.e., the association that the investigator believes may exist between exposure and outcome in the target population. It can usually be posed in the form of a statement or question. Consider the example from Chapter 6 of cigarette smoking as a risk factor for myocardial infarction (MI), or heart attack. The research hypothesis might be expressed in terms of either a statement (“Cigarette smoking increases the risk of subsequent MI.”) or a question (“Does cigarette smoking increase the risk of subsequent MI? ”).
