Structural porosity of differently cross-linked scaffolds expressed by means of differing 2D and 3D parameters. Statistically significant differences are evident between each of the 6 different porosity parameters of each scaffold before and after the differing cross-linking procedures except for those pairs denoted by open circle (Kruskal–Wallis, Bonferroni procedure, 0.05)
