Figure 1 .
Serum bone specific alkaline phosphatase (BALP) concentrations (U/l; square root) in very low birthweight infants receiving corticosteroid or not over the study period. The asterisks indicate significant increase or decrease in serum BALP concentration compared with the pretreatment (Td-pre) or week 3 (Twk-3) levels within the same group. The parentheses indicate a significant difference in serum BALP concentration between the two groups when the corresponding time periods are compared. Results are expressed as mean and SEM.
