  • Study design adjusts for matching characteristics of gestational age, birth hospital, and month of birth.

  • a Coefficient represents adjusted OR (aOR) for every increase in 100 g.

  • b Interaction between age at discharge and delivery. Coefficient represents aOR for each additional day in length of stay.
