Hi Everyone,

Above is my survival data set. and I want to have hazard rate and 95%CI for each level of 'group'.Can I use proc lifetest or proc phreg to have my results?

Thanks so much for your help,

Xinjian

I have tried below sybtaxes (status: 1=stroke, 0=no stroke)

proc lifetest data = want plot= survival (nocensor failure );

time time*status(0);

strata group ;

run;

proc phreg data=want;

class group (ref='1');

model time*status(0)= group/ rl ;

run;

I just cannot get Hazard rate (I don't get hazard ratio) and 95% CI for four levels of group. The output shoulb like this table below.

group	N	stroke	Hazard rate	95%CI
1
2
3
4

Is it possible SAS 9.4 can give results like above?

THanks,
