# Assumed attribution of one-fifth of total intervention cost to each quintile; * Dominant interventions result in health gains and cost-savings; 95% UI = 95% uncertainty interval based on 2000 simulations; AUD = Australian dollars; BMI = body mass index; HALYs = Health adjusted life years; ICER = Incremental cost-effectiveness ratio; kJ = kilojoule; 1 kilocalorie is equal to 4.184 kilojoules; M = million; Q = SEIFA IRSD quintile.
