CMH P-Value

[chinna0369]

Hi all, 

I want to take "Stratified Cochran-Mantel-Haenszel Test P-value" from proc freq. So I am using below procedure for that.

ods trace on;
ods output CMH=cmhpval;

proc freq data=xxx;
tables ACCRES*TRT01PN*ACCGR0FL / norow nocum cmh;
run;

ods output close;
ods trace off;

So I am getting below output.

So which value I need to choose from these three?

Thanks,

Adithya

It depends. Read the documentation for these statistics. If your variables TRT01PN and ACCGR0FL are both ordinal, you should go for the "Stratified Spearman"  correlation labelled "Nonzero Correlation". If either variable is nominal,, go for the "General Association" measure.
