Table 3:
Multivariate analysis to create a model for whole bone strength using all pooled samples (n = 31, some parameters were not complete across the dataset and unable to be included). Each column represents a model using all non-grayed out parameters, with reported β-coefficients for each parameter and each model’s Adj. R2, p-value, and maximum VIF. Moving left to right, a backwards stepwise regression is performed. The final model with three parameters is highlighted, and each individual variable for the final model is also presented alone.
