Univariable analysis in Cox regression

I am using a Cox time to event model and wanting to do an univariable analysis. Is there a macro for that or do I have to test each variable one at a time?

Can you show the code you have for one variable so far? Different approaches have different limits.

Sure, the following is for the predictor sex for example:

proc phreg data=suicide covsandwich(aggregate);

class sex(ref='male')

model time*event(0) = sex/ties=breslow;

run;
