How Can I Customize Kaplan-Meier Failure Plot with proc LIFETEST?

Hello, All:

I am trying to create Kaplan-Meier Failure Plot with proc LIFETEST.

I have 2 questions about this.

No.1

Sample code is below.

data bmt;
    set sashelp.bmt(where=(group eq "AML-Low Risk"));
run;

options nonumber nodate papersize="A4" orientation=landscape;

ods rtf style=journal;
ods graphics / noborder;
ods select failureplot;
ods noproctitle;
proc lifetest data=bmt plots=(survival(failure atrisk(maxlen=13)));
    time t*status(0);
    strata group;
    title " ";
run;
ods rtf close;

About the output, I would like to delete 3 default titles, "The SAS System", "The LIFETEST Procedure", and "Stratum 1: Disease Group = AML-Low Risk".

As you see my code, I used TITLE statement & ODS NOPROCTITLE, and deleted two, "The SAS System", "The LIFETEST Procedure", but the last one, "Stratum 1:~" is not.

Do you have any ideas to delete the last one?

No.2

I would like to customize default label, "At Risk", which expresses the label of # of subjects at risk.

In order to solve these problems, I refered some papers (Kuhfeld WF, et al. -2014-, Geaty H -2015-, etc.) and tried to customize the template, "Stat.Lifetest.Graphics.ProductLimitFailure", but I have no ideas where should be changed.

Thank you in advance.

Unfortunately I think you’re stuck modifying the templates for failure plots.

https://documentation.sas.com/?cdcId=pgmsascdc&cdcVersion=9.4_3.4&docsetId=statug&docsetTarget=statug_kaplan_sect015.htm&locale=en

You can try the macros here as starters to figure out what to change. Or you could rebuild the plots from scratch and customize as desired.

Thank you, Reeza.

I added following code to template "Stat.Lifetest.Graphics.ProductLimitFailure", and I think solved.

DRAWRECTANGLE statement & DRAWTEXT statement

(I do not change original label "At Risk", just overlapped rectangle and comment box lol)

I have no ideas where to be customized template or ATRISK option in proc LIFETEST.

Anyway, thank you!

Remember to undo the changes to your template for your next run!
