Cochran-Armitage Trend Test (2×2) in SAS

Hi everybody,

How can I perform a Cochran-Armitage Trend Test (2×2) in SAS? Especially I’m looking for a tutorial video. I will be grateful for any recommendation.
Thank you for your time.

I think it is an option in PROC FREQ. So you are trying to find a trend difference between two groups across two time points?
