How to calculate the HR and 95%CI of continuous variable in surveyphreg

Jie111 — Fri, 08 Oct 2021 19:10:47 GMT

I want to calculate the HR and 95%CI with one unit increase in variable A using proc surveyphreg.

However, there is no output for the confidence interval.

In some files, they suggested to use HAZARDRATIO to output CI, however, there is no this function in my SAS version.

Is there any other solutions? Thanks in advance.

What version of SAS/STAT do you have?
You can use an ESTIMATE or other type of statement I believe but it depends on your version.
You can find the version using:

proc product_status;run;

Should be something like SAS/STAT 14.3 or 15.1

I'm also assuming you've tried the CLPARM option on the MODEL statement which will give you the CI for the estimate, you'll need to do the log transformation yourself but that's easy enough.
