Trial of Indomethacin Prophylaxis in Preterm Infants (TIPP)

Summary

This trial was to determine whether giving low-dose indomethacin to infants weight 500 to 999 grams (approximately 1 to 2 pounds) at birth improves their survival without cerebral palsy or developmental problems at 18 to 22 months of age.
