The sources of information concerning treatment of febrile seizures in our recent study were medical records written at the time of treatment of an initial or later febrile seizure, the nine scheduled interval histories, and a full history of the child's medical experience recorded when registrants reached the age of 7 years. However, information on drug usage, unlike the remainder of the information utilized in these studies, was not based upon structured portions of the questionnaires and was not systematically available for all registrants.
