Fig. 5. Linear regressions of mineral content on material properties in vertebral cartilage from M. californicus. (A) Strength (MPa) increases significantly as mineral content increases (R²=0.64; P<0.001). (B) Stiffness (MPa) increases significantly with increased mineral content (R²=0.36; P<0.001). The red line is the regression line and the gray lines bounding it are the 95% CI. These regressions include data from control vertebrae and those that were demineralized in EDTA.
