Data are shown by mean ± standard deviation for continuous variables and percentages (%) for categorical variables. BMI – body mass index; SBP – systolic blood pressure; DBP – diastolic blood pressure; LDL – low-density lipoprotein; HDL – high-density lipoprotein; HbA1C – glycosylated hemoglobin; eGFR – estimated glomerular filtration rate; PTH – parathyroid hormone.
