Compressive modulus of various porous hydrogels at equilibrium swelling as a function of porogen content (a), and as a function of porogen particle size (porogen content is 75% for these scaffolds) (b). Data represent mean±SD (n=5). * p<0.01 compared to nonporous hydrogel. # p<0.01 compared to scaffolds with 80% porogen content.
