  1. *IRR, incidence rate ratio.
  2. For each model, the reference group is children with no birth defects.
  3. Adjusted for gender, gestational age, season of birth, mode of delivery, number previous pregnancies, per cent optimal birthweight (POBW), maternal age, maternal asthma during pregnancy, maternal smoking during pregnancy, and socioeconomic indices for areas accessibility/remoteness index of Australia [11].
