Rate of increase in the length of the lower leg (mm/week) in very low birthweight infants receiving corticosteroid or not over the study period. The asterisks indicate a significant increase or decrease in growth of the lower leg compared with the treatment period (Td-pre–Td-end) or week 3–6 of postnatal age (Twk-3–Twk-6) within the same group. The parentheses indicate a significant difference between the two groups when the corresponding time periods are compared. Results are expressed as mean and SEM.
