Structure-function correlations: correlations were tested among mechanical properties and biochemical contents. R2 values are listed for significant correlations. The aggregate modulus, tensile modulus, and ultimate tensile strength were individually compared to the GAG/wet weight, collagen/wet weight, pyridinoline/wet weight, and pyridinoline/collagen, matched by location. Significant, positive correlations were observed between tensile modulus and both pyridinoline/wet weight and pyridinoline/collagen, as well as between ultimate tensile strength and pyridinoline/collagen.
