  • Values are median (range).

  • p Values indicate whether SDSs are significantly different from zero.

  • 1-150 One boy had a bone area measurement and two girls had height measurements that were too small compared with the reference material to calculate the SDS.

  • BMC, bone mineral content; BMD, bone mineral density.
