- aThe statistical models were adjusted for the cluster-level baseline breastfeeding rate and local government area.

- 1. The binary outcome was if the mother was breastfeeding her baby at 6 weeks postnatally (response value = 1) or not (response value = 0)
- 2. The intervention effect for the binary outcome is the odds for breastfeeding at 6 weeks postnatally in the NOSH intervention group compared to the odds of breastfeeding in the control group with an odds ratio > 1 favouring better outcomes (higher odds of breastfeeding) in the intervention group
