Problem: Suppose that you wanted to design an investigation that examined the association between energy drink consumption and cardiac arrhythmias (irregular heartbeat). You decide to utilize a study in which subjects are classified according to their exposure to a factor of interest (energy drink consumption) and then are observed over time to document the occurrence of new cases (incidence) of disease (arrythmia). The measure of association used in this type of study is:
- the sampling error
- the odds ratio (OR)
- point estimate
- the relative risk (RR)
- the efficacy determination
