Sensitivity and specificity for identification of incident vertebral fracture according to L3 Vertebral strength, CT-based aBMD, and trabecular vBMD thresholds (95% confidence intervals in parentheses)

	Vertebral Strength (from CT-FEA) [17]	CT-based aBMD (from CT)	Trabecular vBMD (from CT) [17, 29]
Threshold/cut point	Women: ≤ 4500N Men: ≤ 6500N	t-score ≤ −2.5	vBMD ≤ 80 mg/cm³
Sensitivity	0.46 (0.27-0.67)	0.23 (0.09-0.44)	0.27 (0.12-0.48)
Specificity	0.87 (0.76-0.94)	0.94 (0.84-0.98)	0.81 (0.69-0.90)
Pos. Predictive Value	0.60 (0.36-0.81)	0.60 (0.26-0.88)	0.37 (0.16-0.62)
Neg. Predictive Value	0.79 (0.68-0.88)	0.74 (0.63-0.84)	0.72 (0.60-0.83)
