EURAP: an international registry of antiepileptic drugs and pregnancy.

Editor’s note—Several pregnancy registries presently are collecting data on pregnancy outcomes in women with epilepsy. Such registries have inherent limitations of selection bias and incomplete information. Data from the registries cannot easily be combined to achieve greater statistical power, since each registry differs from the other in methodology. Nevertheless, in the likely continued absence of randomised prospective trials in this field, the registry information comprises a potentially useful data set. Epilepsia therefore, at the suggestion of Dr. Martha Morrell, has agreed to publish occasional updates on the Epilepsy and Pregnancy Registries, submitted in summary form by the registries. The following material is the first such update.
