How to limit survival time in a proc lifetest graph?

[Medidata]

Hello,

I am an SAS layman user, a medical student with very limited use. I have been able to understand and make Kaplan plots for my data. Most of my data is concentrated between 0 to 60 months (five years) but there are some cases that extend to 200 months which makes my main data look small and unfocused. I have been trying to limit this to just 60 months. How should I code and proceed? I would love to have a very simple and layman's explanation since I have no proper coding experience.

I am using this code [proc lifetest data=WORK.IMPORT plots=survival (cl test atrisk(maxlen=13)=0 to 60 by 12);
time 'Survival months'n*Vitalstatus(0);
strata Stage;
run;]

This is the kind of plot I get.


I want only 60 months of survival time. What addition should I add to the above code to limit it?

Thanking you in anticipation.

Try the MAXTIME=60 option on your PROC LIFETEST statement.
