Study	Reason for exclusion
Moriarty 1994	Moriarty et al described a double‐blind, placebo‐controlled trial of a new pharmacological agent, eltoprazine. We excluded this study because not all the participants in the trial were suffering from epilepsy
Myrstener 1968	This report appeared to describe the carbamazepine treatment of epileptic psychosis. However, we could not find this study, as the publication was from the 1960s and the authors could not be reached at the address provided in the abstract
Reid 1981	This trial involved the treatment of overactive, severely mentally handicapped people with carbamazepine. Not all the participants included in the trial were suffering from epilepsy. The trial included people with "profound" mental disability, and diagnosis of psychopathology was not according to standardized diagnostic criteria
