†
The SUID mortality rate included Unexplained Infant and Explained Infant Suffocation cases. SIDS cases were captured within the Unexplained Infant category.
‡
Due to the low frequency of infant SUDEP, infant and child SUDEP cases were considered together, and live birth and child populations were combined as the denominator to calculate a pediatric SUDEP mortality rate.
§
Other nonexertional activities: bathing, riding in a vehicle, eating, receiving medical treatment, voiding, etc.
