Baseline and final laboratory values of the subjects.

25 (OH) D, s-25-hydroxyvitamin D; 1,25 (OH)2D, s- 1,25 dihydroxyvitamin D; PTH, p-parathyroid hormone; Ion Ca, p-ionized calcium; Mg, p-magnesium; phosphate, p-phosphate; T. alk. phosp, s- total alkaline phosphatase; B. spec. alk. phosp, s-Bone specific alkaline phosphatase; FGF23, p- fibroblast growth factor 23; U phosp, urinary phoshate excretion; U Ca, urinary calcium excretion.
n = number of subjects in each group. SD standard deviation. p = plasma, s = serum.
Within group comparisons was performed by Matched Pairs Test. When not normally distributed Wilcoxon signed rank test was applied (Ion Ca and mg), and variable described by median and range (0–100%).
* = P<0.05∶16 week measurement was significantly different from 0 week.
Between groups comparisons was performed by unpaired T-test. Difference between placebo and cholecalciferol group (mean difference). When unable to achieve normal distribution Mann- Whitney’s test was used (Ion Ca and Mg).
* = P<0.05: cholecalciferol group significantly different from the placebo group.
