In addition, another study, including 80 peritoneal dialysis patients with DM or non-DM, evaluated VC using XP in the abdominal aorta and found that a higher serum Mg level was associated with decreased AAC after adjusting for age, serum P, PTH, LDL-C, smoking history, and diabetes [6]; the serum Mg level was 0.84 mmol/L, which is almost the same as that in our cohort but is lower than that in the hemodialysis population [30–33]. This evidence concerns the gene PTH and diabetes mellitus.
