Results are mean (SE).
↵2-150 p < 0.0001 compared with control term infants;
↵2-151 p < 0.0008 compared with study group without insulin treatment;
↵2-152 p < 0.05 compared with study group without RDS (respiratory distress syndrome). p values were calculated with Student's ttest using the Instat program for Macintosh computers.
