Table 5.

Area-under-the-curve (AUC) values from ROC analysis (unadjusted variables), and the associated sensitivity values for two clinically relevant values of high specificity (90% and 95%).

Variable	AUC	p-value*	Sensitivity (%)
			90% Specificity	95% Specificity
LS aBMD	0.76		43	30
FN aBMD	0.65		30	21
Integral vBMD	0.83	0.05	44	38
Vertebral Strength	0.83	0.02	52	37
Load-to-Strength Ratio	0.82	0.05	52	37
Strength-to-Density Ratio	0.77	0.74	30	24

See Table 1 for legends.

^*p-value is for comparing the AUC value against that for LS aBMD; not performed for FN aBMD.
