Area Under the Curve (AUC) for Receiver Operating Characteristic Curves for Each Calculator and BMD

Calculator/variable	Hip fractures AUC (95% CI)	MOFs according to FRAX AUC (95% CI)	Garvan‐defined osteoporotic fractures AUC (95% CI)
FRAX	0.841a (0.795–0.887)	0.708 (0.675–0.741)	N/A
GARVAN	0.769 (0.702–0.836)	N/A	0.721b (0.693–0.749)
BMD	0.811 (0.761–0.862)	0.686 (0.653–0.718)	0.678 (0.647–0.707)

BMD = bone mineral density; CI = confidence interval; MOF = major osteoporotic fracture; N/A = not applicable.

Data are area under the curve (95% confidence interval).

^a p value 0.01 (FRAX's AUC compared with GARVAN's AUC).

^b p value <0.001 (Garvan's AUC compared with BMD's AUC).
