a To extrapolate from the AI for adults to an AI for children, the following formula is used AIchild= AIadult (F), where F = (Weightchild/Weightadult)0.75 (1 + growth factor). To extrapolate from the AI for infants ages 0–6 months to an AI for infants ages 7–12 months, the following formula is used: AI7–12mo = AI0–6mo (F), where F = (Weight7–12mo/ Weight0–6mo)0.75.

b ALT = alanine aminotransferase.
