Results are shown for non-normally distributed parameters as median with the 1st and 3rd quartiles (Q1–Q3), and for normally distributed parameters as mean ± standard deviation (M ± SD). CC, craniocaudal; VD, ventrodorsal; C, cervical; T, thoracic; L, lumbar; * Quantitative computed tomography (QCT) measurements; T, independent Student’s t-test; C, chi-squared test; M, Wilcoxon-Mann-Whitney test.
