  • Calcium was measured in the abdominal aorta, in the left carotid artery, and in plasma. MGP was measured in plasma using the Biomedica assay. All values are expressed as mean ± SD per group of 6 animals.

  • * Significant differences (P < .01) compared with controls (compared with the same time point).

  • Significant differences (P < .01) compared with the W&K diet.
