I would STRONGLY recommend that you talk to your local statistician.
Further:
1. R-help is not a statistical consulting forum
2. Remote statistical consulting is very risky due to the inherent
difficulty in communicating all essential context of the problem and data.
You have been warned!

Hi,
I'm hoping that someone will be able to help. I would like to compare how
covariates associate with the risk of a binary outcome during two periods.
Period 1 will be non-exposure to a treatment and period 2 will be exposure

At the risk of oversimplifying the study design, this sounds like a two
sample comparison of proportions, in which case power.prop.

My question is that I want to do a comparative study in order to compare the
