Table 1.

Number of specimens used for the measurement of s-GAG, hydration and changes in thickness and mechanical behavior.

	Number of specimens used for s-GAG and hydration measurements
	Control	Buffer-treated	Enzyme-treated
s-GAG	n = 6	n = 6	n = 6
Hydration	n = 6	n = 6	n = 6
	Number of specimens used for the measurement of thickness and mechanical behavior changes
	Control/Buffer-treated	Buffer-treated/Enzyme-treated
Mechanical changes	n = 5	n = 7
Thickness change	n = 8*	n = 9#

The * denotes that 5 of the 8 specimens used to measure the thickness change were used for mechanical testing. Similarly, the ^# denotes that 7 of the 9 specimens used to measure the thickness change were subjected to mechanical testing.
