Table 4. Occurrence of bone in scaffold pores.

The ratio of the occurrence of any amount of bone tissue within the pores of a sample to the total number of samples evaluated for each region and material group. The overall ratios for each material group and the percentage occurrence in sections are presented in the last two columns.

Material Group	Top	Middle	Bottom	Overall	In sections (%)
PPF/PF-DA Polymer	6/6	6/6	3/4	6/6	69.2
PPF/PF-DA Macrocomposite	2/4	5/5	4/5	6/6	65.0
PPF/PF-DA Nanocomposite	4/4	5/5	4/4	5/5	63.9
PPF Degradation Control	2/3	1/4	1/4	3/4	22.6
Total	14/17	17/20	12/17	20/21	57.9
