===================================================
 
My favourite biostatistician says: "There are two things not to look
at in the -logistic- output, the standard error and the Pseudo R2."
The confidence interval in -logistic- is calculated from the standard 
error of log(OR), as displayed by the -logit- command. The "standard 
error" displayed in logistic is not this original standard error, and 
it is not used for calculating the confidence interval of the OR 
estimate. So it is pretty useless, I believe.
 
Hope this helps
