Note:
*
after a finding indicates the 8 findings commonly found in subjects without LBP;
**
indicates the 6 findings that are less common but are potentially clinically important.
ˆ
indicates the RadLexID for spondylolisthesis. Any Stenosis refers to stenosis at any location (Central, Foraminal, or Lateral Recess) or not otherwise specified. Any Degeneration refers to any of Disc Degeneration, Facet Degeneration, or Degeneration not otherwise specified. LBP = Low Back Pain.
