Table 3.

The cutoff points of FRAIL-NH to classify three-class frailty (Non-frail vs Pre-frail vs Frail) based on FI

Frailty class	FI	FRAIL-NH
Frailty class	Cutoff points	Cutoff points	VUS (95% CI)	CCR₁(%)	CCR₂ (%)	CCR₃ (%)	Youden Index
Three-class	0.08, 0.25	0, 4	0.68 (0.57–0.76)	80.0	66.1	66.1	0.58
	0.10, 0.21	0, 4	0.62 (0.55–0.72)	65.0	67.9	60.7	0.56
	0.20, 0.45	1, 9	0.76 (0.70–0.81)	70.9	64.3	88.2	0.69

FI Frailty Index; VUS volume under the ROC surface; CI confidence interval; CCR correct classification rate
