Values are median (interquartile range). No data are given for the ascending aorta because calcium scores at baseline were zero in 71 of 80 participants.

HDL-C = high-density lipoprotein cholesterol; LDL-C = low-density lipoprotein cholesterol; other abbreviations as in Table 1.

  • p values are 2-sided after square root transformation.
