Table 2.

Original Sample and Bootstrapping Kappa Agreement Testing (Original vs. Modified Frailty Phenotype Measures) (N=1,833).

	Comparison on Local Mutual Information
Original versus Modified	I_agreement	Mutual Information	Result (P value)	Kappa (95% CI)	Weighted Kappa (95% CI)
(Non-Frail, Pre-Frail, Frail)	1.04	0.86	Agreement (P < 0.001)	0.84 (0.81, 0.86)	0.86 (0.84, 0.88)
(Non-Frail, Pre-Frail, Frail)		0.86^B (0.81, 0.91)^B		0.84^B (0.81, 0.86) ^B	0.86^B (0.84, 0.88) ^B

Note: B = estimates and confidence intervals based on 1,000 bootstrapping samples.
