^*T-score values are given as the mean and standard deviation and are shown with the proportion of patients in the group with a T-score of ≤−2.5 SD for the given region. Bold indicates significant p values, with lower T-scores or higher proportions of patients with a T-score of ≤−2.5 SD for the fracture group compared with the control group.

^†P < 0.05, and

^‡p < 0.01; significant difference by Wilcoxon signed-rank test.

^§P < 0.05, and

^§§p < 0.01; significant difference by Pearson chi-square test.
