Table 8.

p-values for the comparison of the mechanical outcomes, averaged over all quadrants, between the circumferential and meridional directions, in the control, buffer-treated and enzyme-treated groups. Paired Student's t-tests were used for statistical analysis.

Control Buffer-treated Enzyme-treated
Low-pressure stiffness <0.005 <0.0001 0.09
High-pressure stiffness 0.13 <0.0001 0.65
Transition strain <0.05 0.054 0.75
Hysteresis 0.60 0.55 0.79
Initial creep rate (first 80 s) 0.90 <0.05 0.24
Final creep rate (after 80 s) 0.39 0.001 0.59
