st: Missing Value & Logistic regression

[Xavi Barber <xbarber@altern.org>]

Dears stata users:

        I'm doing  a logistic regression, and now i have ajusted  by sex,
age and others variables.

        My question is:
                My old model: xi:logistic esofago i.sexo1 i.edad3c
i.estudi3c i.tipobeb2 i.fuma1  if fil_bebe==1
                My new model: xi:logistic esofago i.sexo1 i.edad3c
i.estudi3c i.tipobeb2 i.fuma1  i.fumatipo if fil_bebe==1

                but the problem is that FUMATIPO have 242 missing values.

                I need to put the result in a typical journal table -->
Case - Control  ; Mean (stad. desv)  ; OR  IC(OR)

                but, i can to compare the 1st model vs then 2nd model??


thanks
