Side-artifact correction (linear regression from Fig. 4A used assuming a constant tissue density of 2.0 g/cc) applied to the modulus-density data reported by Morgan et al. (2003). Side-artifact correction resulted in a substantial increase in modulus for data (A) pooled across multiple anatomic sites and (B) the vertebral body, but did not appreciably change the overall trends of the power law regressions. These data suggest that side-artifact correction can be very important for correcting the magnitude of modulus or yield stress, but may not change the interpretation of results when comparing structure-function relationships across groups (e.g. anatomic site or treatment).
