Figure 4

Average pore sizes of bone substitutes Average pore sizes of individual test samples were determined upon Micro-CT-scanning as described in the Materials and Methods. Each dot represents an individual test sample, and lines indicate the average value. The table below the figure shows the outcome of the pairwise comparisons (Student's T-test with Bonferroni correction). *, p < 0.05; **, p < 0.01; ***, p < 0.005; ns, not statistically significantly different. Grey boxes represent the self-self combinations, which could not be tested.
