Modifying survival plots using PROC GPLOT

Psychiatrist — Fri, 23 Nov 2018 19:54:22 GMT

Hi all,

Would appreciate some help/reference with my code.

I am trying to modify kaplan-meier (survival) curves using ProcGPLOT.

I am not experienced with Macros so would prefer to refrain from that at the moment.

My current code is as follows:

ods output homtests=homeT;
proc lifetest data=Dataset.CUD_surv_Final outsurv= LTEstimates;
TIME duration_time*lMAUD5(0);
strata Nethrace;
run;

goptions reset=all;
axis1 label=(angle=90 'Cumulative Probability of Transition to CUD') order=(0.0 to 1 by 0.25) ;
axis2 label=('Time Since Onset of Cannabis Use (Years)')order=(0 to 60 by 10) ;
proc gplot data= LTEstimates;
plot lMAUD5 * duration_time = NETHRACE / vaxis=axis1 haxis=axis2; ;
run;
quit;

This is not giving me plots as outputs..Can someone lead me in the right direction?

Thanks

"This is not giving me plots as outputs" - Then what is it giving you? Warning or Error messages?

Look at the survival macros in the documentation to modify the curves coming out of lightest. They are well documented and core the majority of use cases. It's not clear what plot you'd get here that would be different than the survival plots.
