Lower serum magnesium is associated with vascular calcification in peritoneal dialysis patients: a cross sectional study

Table 3 Multiple linear regression: the independent association of serum Mg with vascular calcification

Model	Adjusted R ² of the model	Unstandardized coefficient (B) for Mg	95% CI	P value
1	0.34	−10.98	−17.40, −4.56	0.000
2	0.35	−11.50	−17.93, −5.06	0.000
3	0.18	−12.27	−19.54, −5.00	0.001

Model 1: Adjusted for age, serum phosphate, LDL cholesterol, iPTH, smoking history, and diabetes
Model 2: All pre-specified variables in Table 2 were included in the model
Model 3: Adjusted for the variables in model 1; patients with an aortic calcification score of 0 (N = 12) excluded from the analysis
Abbreviations: LDL low density lipoprotein cholesterol, iPTH intact parathyroid hormone
