Table 2. Receiver operating characteristic curve to determine sensitivity and specificity for femoral neck and total hip cut-off values categorized by an aBMD cut-off value of <0.60 g/cm² at the DF or PT.

						Sensitivity (%)		Specificity (%)
Region	AUC	Std. Error	P-value	95% CI Lower	95% CI Upper	T-score_WHO	T-score_YI	T-score_WHO	T-score_YI
TH	0.95	0.021	<0.0001	0.911	0.995	94	81	80	92
FN	0.92	0.027	<0.0001	0.868	0.974	69	69	90	86

DF, distal femur; PT, proximal tibia; TH, total hip; FN, femoral neck; AUC, area under the curve; ROC: receiver operating characteristic; CI: confidence interval; T-score_WHO: World Health Organization T-score criteria of −2.5 SD below the young adult reference mean used to diagnose osteoporosis; T-score_YI, Youden Index T-score cutoff of −3.1 SD at the TH and −2.4 SD at the FN.
