Figure 1 (A) The relationship between coronary artery calcium (CAC) scores from duplicate electron beam computed tomography scans. No subjects with a CAC score >10 Agatston U had a second CAC score = 0 Agatston U. (B) Concordance of calcium classification (i.e., both scores being above or below a given threshold CAC score) for subjects in different body mass index (BMI) categories.
