  1. Mean ± SD, median (IQR) presented. Data are presented compared to never-smokers. Mixed model linear regression analysis used to evaluate differences in TBR compared to never-smokers, Mann-Whitney U test to compare aortic calcification to never-smokers. ***p < 0.001,*p < 0.05 compared to never-smokers
  2. TBR tissue-to-blood ratio
