---|---|---|---|
Distal femoral diaphysis | |||

Cancellous area | 0.072 | – | 0.054 |
After adjusting for cortical bone cross-sectional area, the greater whole bone stiffness in dancers compared to controls remained significant; in contrast, after adjusting for cancellous bone cross-sectional area, this difference was no longer significant
