  • * The average daily increments for body weights (g/d and g/kg/d) and the average weekly increment for length, head circumference, and midarm circumference were computed for the period between the time that birth weight was regained and discharge, transfer, death, age 120 days, or until a body weight of 2000 g was reached.
