There were significant differences between the three groups in age (P = 0.001); prevalence of diabetes (P = 0.007) and coronary heart disease (P = 0.014); systolic (P < 0.001) and diastolic (P = 0.006) blood pressure; levels of urinary albumin (P = 0.001) and serum phosphate (P < 0.001), Ca × P product (P < 0.001), hemoglobin (P < 0.001), CRP (P < 0.001), intact PTH (P < 0.001), eGFR (P = 0.001), and serum albumin level (P < 0.001). This evidence concerns the gene PTH and coronary artery disorder.
