How to modify Kaplan Meier survival curves

Befikadu — Sun, 19 Aug 2018 04:46:48 GMT

Hello Everyone,

I need to modify the following code to change the colours of the KM curves into different line patterns (i.e. to avoid the colours) and to change the X-axis interval into 1 year (instead of 2.5).

The dataset and the outputs I am currently getting are attached.

Thank you.

*To draw the KM curves; 
proc lifetest data= survival2 plots=survival intervals=0 to 14 by 1; 
time Years * status(0); 
strata group; 
run;

The Documentation has plenty of examples of costumizing the Kaplan Meier Plot

Another approach is to export the data behing the plot and use PROC SGPLOT like this

proc lifetest data= survival2 plots=survival intervals=0 to 14 by 1; 
time Years * status(0); 
strata group; 
ods output SurvivalPlot=SurvivalPlot;
run;

ods graphics / AttrPriority=None;
ods html style=Journal;
proc sgplot data=SurvivalPlot;
   step x=Time y=Survival / group=StratumNum;
   xaxis min=0 max=12;
   yaxis min=0 max=1;
run;
