Average stress (MPa) at 10% and 70% strain

Strain (%)	GAG+	GAG−	PBS	WR	PBS	SR
10	0.018	0.022	0.013	0.011	0.014	0.018
70	0.708	0.959	0.629	0.462	0.745	0.304

Significantly different (confidence interval > 95%) average stresses between pairs are indicated by shading. Unshaded average stresses had confidence intervals < 95%.
