George, you are (virtually) correct. The crosstabs procedure will give you the Undajusted OR (you are only measuring the effect of IV in DV) but in the logistic regressión you can obtain the Adjusted OR (and allows you to study the effects of IV in presence of other variables which may have effect in the DV). Try to make a logistic regression with DV and IV and the output is exactly the same as crosstabs.

Hello every one I am trying to calculate the odds ratio with the spss.
Should I use descriptive statistics-crosstabs-risk or binary logistic
regression and Exp(B). Isn't Exp(B) the same as odds ratio? I thank you all
in advance.
