Table 2.

Quantitative summary data for radiographic, densitometric, micro-CT, and biomechanical tests. Within column differences in superscript arabic lettering denotes the existence of statistically significant differences in numeric values. NM = not measured. ∞ = not statistically analyzed against this study’s data.
