  1. Clinical outcomes are shown for the EOD, LOD and maternal invasive isolates. Note that we have not shown the 4 stillbirths in this table to prevent identification of individual cases. The mean ± standard deviation is shown for the neonatal gestational age at birth. All other numbers reflect counts (percentage)
  2. EOD Early-onset disease; LOD Late-onset disease
  3. aOne case of EOD had missing information on gestational age
