Pearson Correlation Coefficients (R) and Corresponding p-values for the Correlation Between the Average Normal Femur and the Spatial Distribution of Osteoporosis as Measured by the Relative Decrease in Radiodensity

Pearson Correlation: Relative Decrease in Radiodensity of Osteoporotic vs Healthy Femur	OP	AO
Longitudinal sections: all 10 regions	R=−0.67, p=0.033	R=−0.83, p=0.003
Longitudinal sections: only 9 trabecular regions	R=−0.35, p=0.36	R=−0.64, p=0.066
Oblique sections.: all 10 trabecular regions	R=−0.74, p=0.014	R=−0.61, p=0.059
