Table 3.

Coefficients from statistically significant-independent variables ($p<0.05$) in ordinary least squares models for each DOSI metric. The most influential independent variable for each DOSI metric is bolded. Insignificant variables are empty. Note that for significant variables (e.g. Bone), the coefficients for all categories of that variable are shown even if a particular category (e.g. tibia) is not significant
