Characteristics of study participants stratified by presence/absence of coronary artery calcium defined by Weston or Agatston scores (median (IQR) for continuous variables and proportion for categorical variables).

Characteristics of study participants stratified by presence/absence of coronary artery calcium defined by Weston or Agatston scores (median (IQR) for continuous variables and proportion for categorical variables).按韦斯顿评分（Weston score）或阿加斯顿评分（Agatston score）定义的冠状动脉钙化（coronary artery calcium）有无情况对研究参与者的特征进行分层，其中连续变量以中位数（四分位距，IQR）表示，分类变量以比例表示。
