Values presented are mean ± SD, followed by the number of specimens in parentheses, for any category with three or more specimens. For categories with only two specimens, both values of vBMD are given. For categories with only one specimen, the vBMD of the specimen is given.
ALDI = apparent loss of disc integrity.
