Figure 2

Densities of bone substitutes Densities of individual test samples were calculated from their length, diameter and weight. Each dot represents an individual test sample, and lines indicate the average value. The table below the figure provides an overview of the statistical analysis of 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.
