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.
