Using the Exam 3 data set listed

Using the Exam 3 data set listed below, examine whether SES is acting as a confounder in the relationship between GenX and liver cancer using the modeling (logistic regression) technique. We will use a 10% difference between the crude and adjusted OR as a guideline for presence of confounding. Fill in the table provided in the answer sheet. Remember to only round the estimate at the last step. Estimates should be presented to two digits after the decimal. Table 3. Comparison of Unadjusted OR and SES-source adjusted OR with 95%CIs. Measure Estimate 95% CI Crude OR SES adjusted OR 2.5 points 2.5 points % difference 5 points 7. Examine the results from the table you completed in 6 assessing confounding by SES, with an adjusted logistic regression model. Compare the unadjusted and adjusted Odds Ratio. Is there evidence of confounding by SES of the relationship between GenX and liver cancer, based on the percent difference guideline? Explain. 8. Compare your stratified results with your logistic regression results regarding the variable SES. Based on your results, moving forward, how would you decide to treat the variable SES in your statistical analyses?
