AbstractControl for confounding and evaluation of the potential for uncontrolled confound
ing is necessary to ensure validity in epidemiologic investigations. Well established risk factors that could confound can be handled in a relatively straightforward fashion in the design phase of the study and in statistical analyses. However, new hypotheses regarding potential cofnounders are often raised after data collection is complete. In situations where confounding was not controlled by design or statistical analysis, the issue becomes how to evaluate reported associations in epidemiologic studies when uncontrolled confounding is raised as an alternative explanation.
