How to obtain the 95% confidence interval using Uno's concordance statistics

Hi, 

 

I developed a model using Cox proportional hazards regression. I would like to obtain the c-statistics using Uno's method. I would like to know how to code to obtain the 95% confidence interval. This is the code I have that provides me only with the Uno's c-statistics.

 

proc phreg data= cpm_10.harmo concordance= uno;
class prim_grp (ref = '1') vmet (ref = '0') / param=ref;
model survival *censored_1y(1)= prim_grp vmet lsf / ties=exact;
run;

 

thank you very much for your help,

Anick
