a
A vertebral body was considered influenced by an acute or subacute fracture if either the body of interest or an adjacent vertebral body was fractured.
b
“Other” is used to denote the complement to this case, namely vertebral bodies with no fracture or nearby fracture. Vertebral bodies with a chronic compression fracture could be considered “other” if there were no adjacent acute/subacute fractures.
c
Wilcoxon rank sum test.
