- median (first quartile, third quartile) or number of people (%)
- *: Significant difference in Kruskal-Wallis Test. **: Significant difference by χ2-test
- Two-group comparison: The Mann-Whitney U test was used to compare two groups, and the P value was corrected by the Bonferroni method. a: Statistically significant difference between normal group and decreased bone mass group. b: Statistically significant difference between normal group and osteoporosis group. c: Statistically significant difference between the osteoporosis group and the decreased bone mass group. N.S.: No significant difference in all comparisons
