The NAAED (Controls exposed to LTG) (Indications NOS), 2024
|
prospective cohort
|
Women are interviewed at enrollment, at 7 months’ gestation and at 8 –12 weeks after the expected date of delivery. The computer-assisted interviews include questions on start and stop dates of each antiepileptic drugs taken, dose, frequency and changes in medication.
|
Women were questioned with a computer-assisted telephone interview 3 times and medical records were obtained. The written descriptions in the pediatricians’ examinations were reviewed separately by the clinical teratologist.

The West China Registry (Epilepsy) (Controls exposed to LTG), 2024
|
prospective cohort
|
The use of antiseizure medications on the included patients was registered by doctors and trained researchers.
|
After delivery, the offspring of the Women with epilepsy (WWE) were followed up by pediatricians. Offspring health was assessed by a multidisciplinary team, composed mainly of pediatricians and pediatric neurologists.
|
No adjustment. The exclusion criteria were as follows: (1) intelligence quotient (IQ) <70, ... (4) a voluntary termination of pregnancy of the mother’s personal choice and unrelated to fetal health.
