The Drescher and Schill paper addresses some especially complex
arithmetic for computing AR from case-control. I'll presume that it is
correct arithmetic. The paper doesn't address whether such a computation
is sensible from any but a computational standpoint. Have a look at the
attached article from seven years later. I would urge you, also, to find
literature about AR in the 2000's.

Subject: Computation of Attributable Risks and their Confidence Interval
via logistic regression
I am looking for a SAS program to compute Attributable Risks (AR) and
their Confidence Interval (CI) via logistic regression in a case-control
study. An article "Attributable risk Estimation from case-control data
via Logistic Regression" published in Biometrics 47, 1247-1256, 1991
described the computation of AR and their confidence interval in GLIM.
I am not familiar with GLIM and would greatly appreciate hearing from
you if you have worked or know somebody who have worked in this area
using SAS. If you have any references on methods to compute AR and CI
via logistic regression using SAS, please let me know.
