Values in the table are Spearman’s rho coefficients. : correlation is significant at the 0.01 level; : correlation is significant at the 0.05 level. BMI, body mass index; WC, waist circumference; 25(OH)D, 25 hydroxyvitamin D; PTH, parathyroid hormone; C-Ca, corrected total serum calcium; iPh, serum inorganic phosphate; and Mg, serum magnesium.
