↵*The hormone response was defined as 3 SDs above baseline.
↵†The maximum laboratory glucose concentration triggering epinephrine response was 96 mg/dl (from a young child with a baseline value of 125 mg/dl) and the triggering norepinephrine response was 116 mg/dl (from an adolescent with a baseline value of 125 mg/dl).
↵‡The nadir glucose values ranged from 56 to 67 mg/dl in young children and 58 to 74 in adolescents.
↵§The nadir glucose values ranged from 54 to 68 mg/dl in young children and 46 to 69 in adolescents.
