  1. *AAC grade 0 was used as reference. Values in boldface type are significant (p < .05)
  2. Multivariate Cox proportional hazard analyses were performed using two models: Model 1 included all significant variables in the univariate analyses, and Model 2 included relevant variables using backward stepwise method
  3. AAC, aortic arch calcification; HR, hazard ratio; CI, confidence interval
