How to get 95% Confidence for Hazard Ratio in Competing Risk Analysis

nmas — Wed, 07 Feb 2024 05:57:05 GMT

Hi,

I am new to SAS and undertaking competing risk analysis. This is my code (I generated this by choosing options under Data instead of actually writing the code):

"proc phreg data=LIB.'COMPETING RISK SET UP 3'n;
class sexd / param=ref;
model Follow_time*Status(0)=sexd age charlson
Med / eventcode=1;
run;"

The Results show Hazard Ratio (HR) but I cannot work out how to get the 95% confidence interval for the HR to show in the Results. Does anyone know how to fix this please?

Thanks!

Have you tried the HAZARDRATIO statement with the CL= option?

Thank you for your reply.

Yes, I tried to include CL (see code below):

"proc phreg data=LIB.'COMPETING RISK SET UP 3'n;
class sexd / param=ref;
model Follow_time*Status(0)=sexd age charlson
Med / eventcode=1 CL;
run;”

However, it shows the following errors in the log:
ERROR 22-322: Syntax error, expecting one of the following: ;, ABSFCONV, ALPHA, BEST, CORRB, COVB, DETAILS, ENTRYTIME, FAILCODE,

FCONV, FIRTH, GCONV, HIERARCHY, INCLUDE, INITIAL, ITPRINT, MAXITER, MAXSTEP, NODESIGNPRINT, NODP, NODUMMY,

NODUMMYPRINT, NOFIT, OFFSET, PLCONV, RIDGING, RISKLIMITS, ROCLABEL, SELECTION, SEQUENTIAL, SINGULAR, SLENTRY, SLSTAY,

START, STOP, STOPRES, TIES, TYPE3, XCONV.

ERROR 202-322: The option or parameter is not recognized and will be ignored.

Any help on how to modify the code would be great.
Thanks!

Hi,
Looking at your code I don't see using HAZARDRATIO statement there.

Besides, please post the entire log from the phreg step, not only the error part.
