PPT-Confounding An apparent association between disease and exposure caused by a third factor

Confounder is a variable that is associated with the exposure and independent of that exposure is a risk factor for the disease Multiple regression allows us to add additional variables into our equation holding these additional covariate constantadjusting for confounding. Prepared for:. Agency for Healthcare Research and Quality (AHRQ). www.ahrq.gov. This presentation will:. Describe the key variables of interest with regard to factors that determine appropriate statistical analysis. Prepared for:. Agency for Healthcare Research and Quality (AHRQ). www.ahrq.gov. This presentation will:. Show how to choose concurrent, active comparators from the same source population (or justify the use of no-treatment comparisons/ historical comparators/different data sources). This is hard!!!. Lesson Objectives. To relate the apparent magnitude scale to the brightness of stars.. To perform simple calculations relating magnitude differences to brightness ratios.. To distinguish between apparent magnitude and absolute magnitude. Standard definition of confounding. A confounder is . Associated with the exposure in the study base. Associated with disease in the unexposed . Not in the causal pathway. Criteria for confounding in genetic association studies. General. D must show that act was:. Involuntary. ; and.
