Abstract:
|
The odds ratio and relative risk are functionally related to the population incidence rate, exposure rate, the magnitude of risk, and the sampling design. In this presentation, we examine the statistical properties of the odds ratio and relative risk estimates as well as the variables affecting their inequality, efficiency and the power of testing when both estimators obtained from the same study and from two different studies. The implications of this study are: (1) the selection of the odds ratio or relative risk estimate should be based on which estimator possesses better statistical properties rather than on personal preference, and (2) the "efficiency of estimate" could be applied to devise the optimal sampling strategy, in particular, when the study involves a moderate or high incidence rate where the case-control approach may be no longer superior.
