  • NA indicates not applicable.

  • a TcB measurements were obtained within 2 hours of the designated times.

  • b TcB measurements that were obtained after initiation of phototherapy were not included.

  • c Because the majority of neonates were already exposed to phototherapy up to the age of 96 hours, TcB percentiles are not reported because of the insufficient number of TcB measurements.
