Fig. 2. Yearly incidence of aortic dissection over study interval Incidence of a type A and b type B acute aortic syndrome (AAS), and c out-of-hospital mortality owing to AAS over time; d incidence of all in-hospital cases of AAS until 2020 year end, and of all cases of AAS including out-of-hospital deaths until 2018 year end. Data for out-of-hospital deaths from AAS are complete to only 2018. Rates presented are age- and sex-standardized to the Aotearoa New Zealand population based on 2013 and 2018 census data, with linear interpolation. Shaded areas represents 95 per cent confidence intervals.
