In this context (and not only for multilevel logistic regression models)
the article by Mood referenced to below is also relevant. It shows that
logistic regression estimates are affected by omitted variables even
when these variables are unrelated to the independent variables in the
model. See:
Mood, C. (2010). Logistic regression: Why we cannot do what we think we
can do, and what we can do about it. European Sociological Review, 26,
67–82.
