Table 2.

Uni- and multivariate (adjusted for age at DXA, sex, and prevalent vertebral fractures) hazard ratios for the risk of incident vertebral fractures

Main variable	Hazard ratio per SD decrease in T-score/BMD (CI)
	Unadjusted	Adjusted for
		Age	Age and sex	Age, sex and prevFX
T-score by DXA	1.36 (0.93–1.99)	1.43 (0.98–2.09)	1.57 (1.04–2.38)	1.55 (0.97–2.48)
BMD by QCT	4.07 (1.98–8.38)	3.60 (1.70–7.64)	4.02 (1.83–8.82)	2.54 (1.09–5.90)

Statistically significant hazard ratios are in italics. CI, 95% confidence interval; SD, standard deviation; prevFX, maximum grade of prevalent vertebral fractures according to semiquantitative score by Genant
