Distribution of the average density of coronary artery calcification in patients with chronic kidney disease.
(a) histogram and (b) stacked bar charts according to CKD stages. Q1–Q5 denotes the 1st to 5th quintiles of the average density of the coronary artery calcification. Range of quintiles for the density: Q1, 0.86–2.36; Q2, 2.38–2.79; Q3, 2.81–3.04; Q4, 3.05–3.18; Q5, 3.18–3.33.

Scatterplots of the Agatston score versus (a) total area and (b) density of coronary artery calcification.
R2 for linear regression is 0.99 (a) and 0.19 (b), respectively.

Cubic spline curves for the relationship between serum magnesium level and the coronary artery calcification density.
(a) serum phosphate level < 3.4 mg/dL, (b) serum phosphate level ≥ 3.4 mg/dL. The model was adjusted for age, systolic blood pressure, estimated glomerular filtration rate, and adjusted serum calcium levels. The dashed line represents the 95% confidence interval.
