  1. aLive births only (n= 95,403)
  2. bEarly neonatal death (ENND); term births (n= 86,839)
  3. cp-value for cOR
  4. dp-value for aOR
  5. *The cOR (95% CI) and aOR (95% CI) were calculated with 20-34 years as the reference age group
  6. Gestational age model was restricted to live births only with adjustment for parity, mode of delivery, singleton/multiple deliveries, and number of antenatal visits
  7. Birth outcome model was adjusted for parity, mode of delivery and number of antenatal visits
  8. Early neonatal death model was restricted to full-term infants (gestation ≥37 weeks) and adjusted for parity, mode of delivery and number of antenatal visits
  9. Birth weight model was restricted to full-term infants (gestation ≥37 weeks) and adjusted for parity, mode of delivery, singleton/multiple deliveries and number of antenatal visits
  10. Overall birth defect model was adjusted for parity, mode of delivery, singleton/multiple births and number of antenatal visits. ¥Newborns with at least one of the sixteen major external birth defects of interest to the study
