a
Number of patients for whom data were available on that variable.
b
Prevalences are based on the number of patients with available data for each section of the spine (cervical n=32; thoracic n=29; lumbar n=32). Data on the spine were based on X-ray (n=34), magnetic resonance imaging (n=11), and computed tomography scan (n=1) (more than one imaging method was used in some patients).
c
Data on the hip were based on X-rays (n=30).
