All data are reported as % (95% CI), such that numbers in the table can be considered per 100 infants.
Abbreviations: CI, confidence interval; RBC, red blood cell.
Includes one infant who received cryoprecipitate without RBC, platelet or plasma transfusion.
Data not shown for 18 preterm infants for which gestational age unknown.
Term babies who are missing a birthweight are assumed to be normal birthweight. 10 subjects have a premature diagnosis, but no birthweight-related diagnosis or birth weight, thus they are excluded from this stratification.
Includes 324 patients of American Indian/Alaska Native descent, 62 of Native Hawaiian/Pacific Islander descent, 93 patients of more than one race, 9,307 identified as other race, and 10,650 of unknown race
