proc tabulate multiple variables

[Anita_n]

Dear all, 

I have a table that looks like this: 

drug	period	visit	number_of_patients	percentage	N_Percentage
A	period 1	1	5	16,67%	5(16,67%)
B	period 2	1	10	33,33%	10(33,33%)
C	period 3	2	12	50,00%	12(50,00%)
D	period 1	2	3	12,50%	3(12,50%)
E	period 2	3	15	35,71%	15(35,71%)
A	period 3	3	20	47,61%	20(47,61%)
B	period 1	3	7	16,67%	7(16,67%)
C	period 2	4	5	35,71%	5(35,71%)
D	period 3	4	9	64,28%	9(64,28%)
E	period 1	5	10	76,92%	10(76,92%)
A	period 2	5	3	23,08%	3(23,08%)
B	period 3	1	8	26,67%	8(26,67%)
C	period 1	1	7	23,33%	7(23,33%)
D	period 2	2	7	29,17%	7(29,17%)
E	period 3	2	2	8,33%	2(8,33%)

I wish to include the percentages (that means var should be number_of_patients and percentage or replace both with N_percentage) to the table. I already have the number of patients in there but I wish to add the percentages. This is calculated per visit. Here is my code any help:

proc tabulate data=have format=6.0 style=[font_size=5pt just=c fontstyle=italic borderwidth=0 cellpadding=0 foreground=dimgray];
class drug period visit / order=data style=[textalign=center ] missing;
  classlev drug period visit/ style=[background=white font_weight=bold font_size=5pt foreground=dimgray cellpadding=2];
   var  number_of_patients/;
   keyword all sum /style=[background=white font_weight=bold font_size=5pt foreground=dimgray];

  table ( drug=' '*all=' '*([style=[background=white foreground=dimgray font_weight=bold font_size=5pt]]))*(number_of_patients=' '), 
   sum=' '*period=''*visit=' ' / row=float nocontinued indent=1 rts=2  misstext=[label=" " ] 
   style=[cellpadding=3 font_size=5pt foreground=dimgray] 
   box=[label=' ' style=[background=white foreground=dimgray font_weight=bold font_size=5pt ]];
run;

Try the following revised code:

proc tabulate data=have format=6.0 
style=[font_size=5pt just=c fontstyle=italic borderwidth=0 cellpadding=0 
foreground=dimgray];
class drug period visit / order=data style=[textalign=center ] missing;
classlev drug period visit/ style=[background=white font_weight=bold font_size=5pt 
foreground=dimgray cellpadding=2];
var number_of_patients/;
keyword all sum /style=[background=white font_weight=bold font_size=5pt 
foreground=dimgray];
table drug=' '*period=' ', visit*number_of_patients=' '*(sum=' ' colpctsum=' '*f=8.1);
run;
