Customizing the Kaplan-Meier Survival Plot

Suppressing the Second Title and Adding a Footnote

The following steps add an ENTRYFOOTNOTE statement to the %StmtsBeginGraph macro and suppress the second title:

%ProvideSurvivalMacros

%let ntitles = 1;
%macro StmtsBeginGraph;
   entryfootnote halign=left "Acme Company %sysfunc(date(),worddate.)" / 
                 textattrs=GraphDataText;
%mend;

%CompileSurvivalTemplates

proc lifetest data=sashelp.BMT
              plots=survival(cb=hw test);
   time T * Status(0);
   strata Group;
run;

The results are displayed in Figure 23.28.

Figure 23.28: Footnote but No Second Title

By default, the nTitles macro variable is 2, and all titles are displayed. Setting nTitles to 1 suppresses the second title. You can add titles or footnotes to the plot by adding them to the %StmtsBeginGraph macro. This example adds a footnote that consists of a company name followed by the current date, formatted by using the WORDDATE format. The GraphDataText style element is used; it has a smaller font than the default style element, GraphFootnoteText.
