Table 1.
Results of least-squares regressions for the parametric description of elastic shear modulus (G′) and dynamic viscosity (η′) of the injectable biomaterials (n = 3) and the human vocal fold cover (n = 7)6 according to Equations (1) and (2). R 2 is the coefficient of determination indicating the goodness of curve fitting.
