In addition, age (OR: 0.016, 95% CI 1.00–1.08, P = 0.016), diabetes (OR: 2.07, 95% CI 1.06–4.03, P = 0.033), coronary heart disease (OR: 2.71, 95% CI 1.18–6.24, P = 0.019), systolic blood pressure (OR: 1.29, 95% CI 1.03–1.62, P = 0.030), and serum Ca × P product (OR: 1.05, 95% CI 1.01–1.10, P = 0.001) and intact PTH levels (OR: 1.14, 95% CI 1.04–1.24, P < 0.001) were independently associated with AVC. The gene discussed is PTH; the disease is diabetes mellitus.
