Risk Ratio proc genmod predictor variable has multiple levels

Question

I am using proc genmod to estimate risk ratios. Two of my predictor variables have more than 2 levels. My gender variable is ‘male’, ‘female’, ‘other’ and race is ‘white’,’non-hispanic black’, ‘hispanic’. Here is how I set up the model. I get only 1 risk ratio. Is it possible to risk ratio for each level of the predictor variable? I have not done this before, so any advice is appreciated.

Thanks.

Proc genmod data=rr_genmod;
Class gender(ref=’male’) race (ref=’white’);
Model outcomeA(ref=’1’)=gender race/ dist=binomial link=log;
ESTIMATE 'BETA' GENDER 1-1/EXP;
ESTIMATE 'BETA' RACE 1-1/EXP;
RUN;

I would start with the LSMEANS then perhaps LSMESTIMATE for more complex estimates. The syntax is would be something like this.

LSMEANS GENDER RACE / DIFF CL EXP;

There are other options that may be useful but you should consult the documentation for those details.
