Hi there,

 

I have been struggling with this problem for a while.

 

I run the PROC LIFETEST procedure below to get the KM plot. See the plot in the attachement. However, you will find that the time points along the x-axis are 0, 10, 20, 30, 40, 50, and 60. But I want the time interval to be 12, which can made the time points to be 0,12,24,36,48, and 60, so that the time points along x-axis is same as the time points for the number of at risk listing...I tried many options, even trying to revise PROC TEMPLATE. But none of them works......Does any one have resolved similar problem? Thanks in advance.

 

proc lifetest data=master1 intervals= 0 to 60 by 12
                           plots=survival(test atrisk(outside)=0 to 60 by 12);
  by period;
  strata location;
  time surv_time*Censor(0);
run;

There are about 100 pages of documentation devoted to configuring the KM plot. Try modifying the example in the section "Modifying the axis" to use xOptions instead of yOptions .

Hi Rick,

 

SAS gave me error message after I try this macro...see below

Here's some old code I had- changed it to months. You can read through the comments and make changes as required.

 

/*SAS PROC LIFETEST Survival Plot Template

Modifed by: F. Khurshed
Date: July 27, 2011

Description: I modified the basic GTL plot to 
1) Changed the thickness of the lines plotted
2) Changed the X axis markers to 12 month intervals
3) Changed the Y axis markers to 0.25 level increments
4) Changed the label of the legend to be a macro variable called legend_label. This needs to be specified prior to output
5) Changed the Y axis markers to be formatted to percent using the tickvalueformat option. (2012-05-01 FK)

Hi Reeza,

 

Thanks for sharing. However, this still does not work...It is very very weird that PROC TEMPLATE does not work the plot on my end...

Verify which template your graph is using - remove the atrisk and test statements, leaving survival alone and see if that works. Based on your specifications, it may be using a different template.

 

Use

 

ODS TRACE ON;

code

 

ODS TRACE OFF;

Hi Reeza,

 

You are right, my template name is Stat.Lifetest.Graphics.Productlimitsurvival2. After I updated the name, the code works. But now, the list of number at risk is within the plot..See the attachement. If I want it to be outside of the plot, like below the x-axis, could you mind telling me from which line of your code that I can start to revise. Thank you very much!

@ @ Tiny_Kane Is there a way to modify this macro for doing CIF plot using proc phreg?

 @ Reeza Is there a way to modify this macro for doing CIF plot using proc phreg or proc lifetest? I used this code successfully to reformat the X axis for my survival curve but am now trying to change it for CIF

Yes. You need to read the documentation, which includes instructions on how to download and use the macros.
