Tom,



Adjustment for confounding is a fairly straightforward procedure in 

Epidemiology.  See Rothman's and Greenland's Modern Epidemiology text 

for more details.  There is no algorithm, but rather part of the 

multivariate analysis.  I just looked over the Iowa AJE paper and 

they did check for residual confounding by smoking and did not detect 

any.
