Proc Power: How to add relative risk reduction, control group event rate, and drop out rate

Hello everybody!

 

I am trying to use proc power to create a total # of pateints needed vs. power graph with a control group event rate of 10%, relative risk reduction of 35%, a power of 90%, drop out rate of 0.25, and a alpha of 0.05.  My sample size is 7500 with a 1:1 ratio for each of the two treatment groups. 

 

This is all the information that I have, no datasets to calculate stdevs'. 

 

I was wondering how you can create this graph in SAS? I am having trouble locating information from SAS Global Forum white papers on how to do this. 

 

 

 

Thank you!
