Table 4.
Storage stiffness (k’), loss stiffness (k’’), storage modulus (E’) and loss modulus (E’’) regression analyses. Stiffness coefficients (A and B) are in N/mm while moduli coefficients (C and D) are in MPa. Coefficients for the median trends are provided. p < 0.05 indicates that the logarithmic regression analysis was significant.
