Can modify K-M survival, but not K-M failure using PROC LIFETEST Template

Hi All,

Using the SAS Institute PROC LIFETEST Template I can modify the y-axis to remove extra white space given that survival is >75% in both groups. I also can modify the ticks on the x-axis, etc. But I want a cumulative mortality curve not a survival curve. According to documentation that I've found, all I have to do is change:

Stat.Lifetest.Graphics.ProductLimitSurvival%scan(2,2-&outside);

To:

Stat.Lifetest.Graphics.ProductLimitFailure%scan(2,2-&outside);

And then make the appropriate changes to %let statement between

%ProvideSurvivalMacros

and

%CompileSurvivalTemplates

The only difference is in the %let for yOptions, the first for survival and the second for failure:

*%let yOptions = label="Survival Probability" shortlabel="Survival"

linearopts=(viewmin=.75 viewmax=1

tickvaluelist=(.7 .75 .8 .85 .9 .95 1));

%let yOptions = label="Cumulative Mortality" shortlabel="Mortality"

linearopts=(viewmin=0 viewmax=0.25

tickvaluelist=(0 0.05 0.10 0.15 0.20 0.25));

When I do this, there is no data in the K-M plot, although my options appeared to be implemented. When I delete the failure templates and re-run the proc I get the failure distributions plotted, but without my preferred options, of course.

I have no trouble getting what I want for the survival curves?

Am I missing something on how to modify the y-axis for failure curves without losing the data points in the graphs?

I just can't figure this one out. Hopefully, someone might have experienced this issues and figured out how to do this.

Re: Can modify K-M survival, but not K-M failure using PROC LIFETEST Template

Reeza — Tue, 19 Nov 2019 22:27:31 GMT

Ok...I'll have time to take a deeper look tonight but it seems like your %MEND are not in the correct place. It would help if you formatted the code (autoformat is fine) and posted it in a code block so it's legible. It's hard to follow long blobs of text sometimes when there's no formatting.

Re: Can modify K-M survival, but not K-M failure using PROC LIFETEST Template

greg_maislin — Tue, 19 Nov 2019 22:29:52 GMT

thank you. Yes, I saw that. I replied via e-mail and checked format. It was horrible, so a copied and pasted from program window. Much easier to read.

Re: Can modify K-M survival, but not K-M failure using PROC LIFETEST Template

greg_maislin — Wed, 20 Nov 2019 00:23:14 GMT

So this is what I have discovered. I can create a failure plot using plots=survival(failure). But whenever I attempt to edit the template

Stat.Lifetest.Graphics.ProductLimitFailure such as the y and x axis, titles, and labels, the change I desire are implemented, but a survival and not a failure plot is produced. I thought the K-M plots were missing because I set the y-axis to go from 0 to 0.3 as appropriate for failures, but the survival plot goes from 0.7 to 1 and so there was nothing to plot. Once I change the y-axis to 0.7 to 1.0 I see all my other edits to the failure plot such as labels, etc, but a survival and not a failure plot is printed. I'm beginning to believe this is a bug in my version of SAS.

I even tried a different approach. Even though I am editing Stat.Lifetest.Graphics.ProductLimitFailure, the subsequent call to proc lifetest produces a survival plot and not a failure plot even though I specified plots=survival(failure). If I delete the modified template, then plots=survival(failure) does produce a failure plot. So I am stuck not being able to edit KM failure plots in PROC LIFETEST.

Re: Can modify K-M survival, but not K-M failure using PROC LIFETEST Template

Did you mess around with the original templates? If so, it's possible you accidentally destroyed it. What version of SAS are you using, very specifically.

Run

proc product_status;
run;

Log will show SAS version and STAT version such as

SAS 9.4M6, SAS STAT 15.1

Here is the info. Interesting hypothesis that I destroyed the original
Stat.Lifetest.Graphics.ProductLimitFailure.

When I do ods trace on, I see a template generated. I will run same code
on different computer.

proc product_status;

Start a new session and run the code below, how does the graph look?

proc lifetest data=sashelp.BMT plots=surv(failure atrisk=0 to 2500 by 500);
   time T * Status(0);
   strata Group / test=logrank adjust=sidak;
run;

Does it match the output attached?
