I have this section of a table which compares 2 drugs

smackerz1988_0-1698232232899.png

and this piece of of code (AvalM is Aval transformed to months using this code avalM = aval / 365.25 * 12;)

ods results off;
ods output CensoredSummary=stat00 Quartiles=med00 homtests= logrank00;
PROC LIFETEST data = adtte00 METHOD = km CONFTYPE=LOGLOG plots=survival(atrisk=3 6 9 12 18 24) ;
TIME avalM * CNSR(1) ;
STRATA trtp;
by &Subgrp;
RUN;
ods results on;

Now I know there is an option in PROC LIFETEST for plots such as 

 

plots=survival(atrisk= 0 to 2500 by 500)

Can something similar be done here just to get the results for each month specified and can the by statement be adjusted as the pattern is 3,6,9,12,18,24 so the first 4 are every 3 months but the rest are every 6 months. Any help would be greatly appreciated. 

data have;
input  SUBJID $ AVALM 8. CNSR; 
infile datalines dlm = '|';
datalines;
1001|0.0328542094|0
1002|4.205338809 |1
1003|0.0328542094|0
;
run;

Can not list these months in PLOT ?

 

PROC LIFETEST data = adtte00  METHOD = km CONFTYPE=LOGLOG  plots=survival(atrisk=3 6 9 12 18 24) ;
	TIME t * Status(0) ;
	STRATA Group;
	RUN;

@Ksharp I get the warning and log notes below. Is there a way to just get the results in a data set as opposed to using ODS graphics or would this require additional steps? 

 

"WARNING: ODS graphics must be enabled to obtain the full features of the PLOTS= option.
