  1. Smoking prevalence estimates are from the Australian Health Survey 2014–2015 [19]. Observed rates of CVD mortality are those for all circulatory diseases (rather than any major CVD) in the Australian population [23]. Observed acute coronary syndrome hospitalisations are from national data on hospitalisations for acute myocardial infarction (AMI) or unstable angina in 2013 [24]
  2. RRcs and RRfs used for CVD mortality are the broad age group-specific relative risks for mortality from major CVD among current and former smokers, respectively, relative to never smokers. RRcs and RRfs used for acute coronary syndrome are the broad age group-specific relative risks for fatal and non-fatal AMI among current and former smokers, respectively, relative to never smokers
