Table 3:

Correlations (ρ), between parameters (interparameter), and between model coefficients and measured mechanical properties. No significant interparameter correlations were observed, except for a weak correlation between β and k₂ (ρ=−0.25). E was significantly correlated with mechanical parameters: for circumferential samples, both μ and β had significant relationships to E, but only μ had a strong correlation (ρ=0.91); similarly for axial samples, μ and k₁ were significantly correlated with E, but only k₁ had a strong correlation coefficient (ρ=0.79).
