Independent risk factor associated with VFF

Characteristics	Relative risk (95% CI)	p Value	Score*
Model 1: with BMD (AUC 0.7414)
Age > 65 years	3.93 (2.38–6.51)	< 0.01	4
History of height loss > 1.5 cm	3.05 (2.05–4.57)	< 0.01	3
BMD T-score femoral neck < -1.7	2.15 (1.39–3.33)	< 0.01	2
Model 2: without BMD (AUC 0.7160)
Age > 65 years	4.24 (2.58–6.99)	< 0.01	4
History of height loss > 1.5 cm	3.14 (2.12–4.65)	< 0.01	3

Relative risk and p value were calculated from stepwise logistic regression analysis

Score was adjusted from relative risk

CI confidence interval, AUC area under the curve according to the model

“Score*” used to described that Score was adjusted from the relative risk
