Normal Hemostasis Values in Premature Infants

This study aims to retrospectively determine, in a large cohort of apparently healthy children born before 37 weeks of gestation, the expected values of certain hemostasis parameters from birth to 18 months (when they start walking), and to determine whether or not they differ from those of full-term infants.
