Data are expressed as mean ± SD or median and its interquartile range (Q1–Q3) PTH and 25(OH)D. denotes variables with a significant departure of normality as detected by Kolmogorov–Smirnov and Shapiro–Wilk test and inspected graphically by quartile-quartile plots. T test: independent samples T test; U test: Mann–Whitney U test.
