SAS to do Data Analysis Crude OR and Adjusted OR

Need crude and adjusted odd ratios with the CIs

I have a project where I have to do a data analysis of a cross sectional study looking at a minimum of 4 confounders and 1 effect modifier on top of the exposure using SAS.

I am supposed to run a proc logistic on this to give crude and adjusted odd ratios . My issue is that the variables all have multiple levels such as my exposure is regions. How do I get the Odd ratio for each individual region? My effect modifier is sex, how do I get the individual OR for male and female?

 

Please help! I am so bad at SAS and I need to get the data before I can complete the rest of my project.

Use the oddsratio statement. Check out this example - run the code too!

With one note: set param=REF on your CLASS statement. 

 

If if you’re still uncertain post back with specific questions and your code.

Thank you! But how would I do a stratified analysis to find the individual ORs for each group compared to the outcome?

Do you want stratified logistic regression or are you looking for something like: Men are 1.3X more likely to die before 80 than women?

Stratification is a different process and then you would include that variable in your STRATA statement. 

 

Otherwise, the oddsratio is the number you're looking for here.
