I am reporting absolute risk difference and CI's from proc freq below.

 

I am wondering which CIs and p-value should be reported in the results.

 

There are 2 treatment groups and both Ns > 100. But the events of interest (=1) are < 5. 

 

proc freq data=data;
table trt*event/ chisq riskdiff(cl=( newcombe exact wald) ) pdiff;
run;
