Rate of rise of total serum bilirubin in very low birth weight preterm infants

To assess the postnatal rate of rise (ROR) of total serum bilirubin (TSB) in very low birth weight (VLBW) preterm infants, to determine risk factors associated with a rapid rise (>90th percentile), and to compare ROR and hour-specific TSB at postnatal 12–48？h with data of term infants retrieved from the literature
