Hi guys,

 

I'm trying to use SAS for case-control design.

 

The response variable is 'obese' vs 'nor-obese'.

 

The exposure is defined by number of years of individuals participation in the weight loss program:

durcat 1-participated 1 year 

durcat 2-participated 2 years 

durcat 3-participated 3 years 

durcat 4-participated 4 years 

durcat 5-participated 5 years 

 

proc freq data=have;
tables obese*durcat/cnh gender race age income_category;
run;

 

I found below SUGI paper highly relevant.

MY QUESTION IS:

Do you know other approaches or PROC options than using MACRO with PROC FREQ to conduct case control study as explained above?

Guys,

 

I think I could use proc logistic or proc genmod to estimate RR instead OR. Below guide was very helpful.
