Exporting Klingenberg Confidence Limits from proc Freq

[sizmailyan]

I cannot find the option to export the Klingenberg Confidence Limits or generate the risk difference plots using the COMMONRISKDIFF option in proc freq TABLES statement. Is there a way to accomplish this task?

thank you very much.

The example below shows how to use the PLOTS= option to get the common risk difference plot with the Klingenberg CL.  It also demonstrates how to save the CL to a data set using an ODS OUTPUT statement.

data Migraine;
input Gender $ Treatment $ Response $ Count @@;
datalines;
female Active Better 16 female Active Same 11
female Placebo Better 5 female Placebo Same 20
male Active Better 12 male Active Same 16
male Placebo Better 7 male Placebo Same 19
;
ods graphics on;
proc freq data=Migraine;
tables Gender*Treatment*Response /riskdiff commonriskdiff(cl=k)
plots(only)=riskdiffplot(stats common=k);
weight Count;
title 'Clinical Trial for Treatment of Migraine Headaches';
ods output CommonPdiff=CRD_DS;
run;
ods graphics off;
proc print data=CRD_DS;
run;
