Proc Tabulate Percentages

[js8765]

Hi,

I keep coming to a dead end when trying to find out how to do the following in Proc Tabulate.  I would like to create the percentages as shown in the attached table. You will see that the treatment counts should be calculated as a percentage of the number of patients in each region. 

If anyone could help I would be really happy. I've been trying to solve this for a long time!

Thanks very much in advance!

 Here's the code I have with the variable names.

data all1;
  set all;
  by patno;
  if first.patno then pat_cnt = 1;
run;

proc tabulate data = all1;
  class grp trt region;
  var pat_cnt;
  tables pat_cnt (grp * trt), region;
run;

It would greatly help to provide some example data.

You may be looking for a table statement like

 tables pat_cnt (grp * trt), region*(n pctn);

but can't test that without data.
