Table 6.

Age-adjusted odds ratio and area under the receiver operator characteristic (c-statistic) for bone density, strength estimates and load-to-strength ratio at the proximal femur in age-stratified sample of Rochester, Minnesota men over the age of 35 years.

	No Fracture (n=162)	Any Fracture (n=104)		Osteoporotic Fracture (n=28)

		OR (95% CI)^*	c-statistic	OR (95% CI)^*	c-statistic
Total Hip aBMD (g/cm²)	referent	1.4 (1.1, 1.8)	0.75	2.0 (1.3, 3.0)	0.75
Total Hip vBMD (mg/cm³)	referent	1.6 (1.2, 2.2)	0.75	3.4 (1.9, 6.3)	0.78
Proximal Femur Strength (N)	referent	1.5 (1.1, 2.1)	0.74	3.2 (1.7, 6.2)	0.78
Load-to-Strength Ratio	referent	1.5 (1.1, 2.0)	0.74	2.5 (1.6, 4.1)	0.77

[OR (95% CI) and c-statistic for Osteoporotic Fracture if referent group is considered No Osteoporotic Fractures group: Total Hip aBMD, 1.7 (1.2, 2.4), 0.69; Total Hip vBMD, 2.8 (1.7, 4.8), 0.74; Proximal Femur Strength, 2.8 (1.5, 5.1), 0.74; Load-to-Strength Ratio, 2.1 (1.4, 3.1), 0.74]

Odds ratio per SD decrease for all variables except load-to-strength ratio, which is per SD increase.
