Age, gender, race, BMI, smoker, diabetes status, hypertension status, eGFR, serum triglyceride, LDL cholesterol, HDL cholesterol, calcium, phosphate, PTH, and 25(OH)D levels were included in the model. Linearity, normality of residuals, independence of residuals and homoscedasticity assumptions met. No multicollinearity problem. No significant outliers
