Figure 3. Means and standard deviations of storage modulus G', loss modulus G'', and loss tangent tan at 1.0 Hz. White and black bars are values in A-P and M-L tests, respectively. Error bars are standard deviations (for each group, n = 10). Asterisks: significance of difference between the groups (** p < 0.01; * p < 0.05) as tested with a paired Student t test.
