Change the title in survival plot produced by phreg

[sarahsasuser]

Hi All,

When I ask for plots in proc phreg and use the baseline covariates statement to ask for a direct adjusted plot, the title "Direct Adjusted Survivor Functions" appears. How do I get rid of this? I have tried modifying the title by using ods trace to find the template for the survival graph and modify the proc template code. However, the template 'Stat.Phreg.Graphics.Survival' does not have a title with "Direct Adjusted Survivor Functions." Is this the correct template for this graph? If so, how can I modify the code below to get rid of the title?

Thanks!

Sarah

The SAS/STAT documentation discusses several ways to change the titles (and other features) of the ODS graphics. For the title, you can read the section "ODS Graphics Template Modification: Changing Titles by Using the %GrTitle Macro"

Here is the %GrTitle macro applied to the survival plot in PROC PHREG. The example and data are from the Getting Started example in the doc.

/* Example from Getting Started example for PHREG procedure */
data Rats;
   label Days  ='Days from Exposure to Death';
   input Days Status Group @@;
   datalines;
143 1 0   164 1 0   188 1 0   188 1 0
190 1 0   192 1 0   206 1 0   209 1 0
213 1 0   216 1 0   220 1 0   227 1 0
230 1 0   234 1 0   246 1 0   265 1 0
304 1 0   216 0 0   244 0 0   142 1 1

   baseline covariates=regimes out=_null_;

%let PHReg_Survival = The Title of My Plot;
%let PHReg_Survival2 = An optional subtitle;

This worked! Thanks!
