Table 2.

Correlation coefficients between W-layer finite element parameters (W) and mechanical test parameters and ratio of W-layer to D-layer finite element parameters (W/D) and mechanical test parameters. The last row lists the coefficients obtained between BMD and test parameters. Correlation coefficients are listed with p-values as R(p).
