Table 2.

Multiple regression models relating mechanical outcome measures (bending strength and post-yield displacement) with geometry (section modulus) and tissue density (TMD). Estimate values and significance level of each are listed, along with an overall model fit.

	Summary of Fit (n = 153)	Intercept	Section Modulus (Zmin, mm³)	Tissue Mineral Density (TMD, mg HA/cc)
Femur Bending Strength (N-mm)	r² = 0.88 (p < 0.0001)	-101.9 (p < 0.0001)	159.3 (p < 0.0001)	0.0721 (p < 0.0001)
Post-Yield Displacement (mm)	r² = 0.20 (p < 0.0001)	1.08 (p < 0.0001)	-0.146 (p = 0.579)	-0.000598 (p < 0.0001)
