  1. Results are listed as median with interquartile range (25%;75%)
  2. p-values shows results of statistical tests comparing PTX-treated and non-PTX-treated. p < 0.05 is considered as significant and is marked by *
  3. Abbreviations: PTX parathyroidectomy, eGFR estimated glomerular filtration rate
