According to variable distribution, Mann–Whitney test or Student’s t-test was used to compare the different variables among women with or without a blunted PTH response. : mean ± standard deviation IQR, interquartile range; 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.
