How may I analyze various survival times?

Dear all,

I am new to survival analysis and attempting to perform cox proportional hazards on my database of trauma patients.  I'm interested in identifying the hazard ratio of alcohol exposure for in-hospital death in trauma patients.  My database has patients that die up to 200 days out. I'm interested in examining the hazard ratio in the first 6 hours, 12 hours, and 24 hours of hospitalization.  How may I do this?  Thank you for your help...

Take a look at the Examples in the documentation for PROC PHREG, and see if any fit your situation.  That would give you a start on both code and interpretation.
