**Completed cases are those that had complete record of age, sex, shockable, witnessed arrest, BCPR, AED, location, year of arrest and survival (survival to hospital admission, survival to hospital discharge and neurological survival).

The categories are excluded in sequence. First, ages<18 were excluded, then all 911 witnessed arrests and then the nursing homes were excluded from the complete data.
