  1. Bold format: statistical significance (p < 0.05); t-test, Mann–Whitney test were used.
  2. Continuous variables were expressed as median value and interquartile range [25%ile; 75%ile].
  3. BMI body mass index; SBP systolic blood pressure; DBP diastolic blood pressure; Hb hemoglobin; PTH parathormone; Ca calcium; P phosphorus; ALP Alkaline Phosphatase Prot-U: daily urinary protein excretion; “s” serum; m25OHD mean levels of native vitamin D.
