ALB and Hypoalbuminemia: The model defined frailty as having ≥ 2 of the following: slowness (gait speed < 1.0 m/s), hypoalbuminemia (albumin ≤ 3.5 g/dL), and weakness (grip strength < 28 kg for men, < 18 kg for women).<h4>Results</h4>The simplified model demonstrated high diagnostic accuracy for frailty defined by the Japanese Cardiovascular Health Study criteria (area under the curve = 0.868; sensitivity, 55.8%; specificity, 91.4%).
