RERI estimates using PROC GENMOD or PROC LOGISTIC

[CathyVI]

Hi,

I am working on test for additive interaction on the probability scale. I am able to use PROC NLMIXED for logistic regression and back-transform estimates to form contrasts on the probability scale.

Any chance anyone can help to get the IC= interaction contrast and  relative excess risk due to interaction
(RERI) using PROC GENMOD or PROC LOGISTIC?

This is my sample data:
