Using an imputed dataset, I am replicating logistic models run in a previous version of Stata (8.0) using Stata 12.0. <mi describe> and <char li> confirm the correct n=2655 in my dataset, and the correct number of clusters is also confirmed in my model output.

The original (Stata 8.0) model looks like:

mim: logit boutcomeyn age gender, vce(cluster id_sc) or

However, whether I run <logit..., or> or <logistic> as follows I am getting (the correct) coefficients rather than odds ratios as output.

mi estimate: logit boutcomeyn age gender, vce(cluster id_sc) or
mi estimate: logistic boutcomeyn age gender, vce(cluster id_sc)

Why is Stata not giving me odds ratios as output?
Thanks in advance for any guidance.

You want to use the eform option for mi estimate. As the manual entry for mi estimate says,

eform option; see [R] eform option. Regardless of the estimation command specified, mi estimate reports results in the coefficient metric under which the combination rules are applied. You may use the appropriate eform option to redisplay results in exponentiated form, if desired.
