Phase angle obtained by bioelectrical impedance analysis independently predicts mortality in patients with cirrhosis

Table 2 Mortality estimates for patients with cirrhosis from a multiple Cox regression model

Variable	HR (95%CI)	P value
Age (yr)	1.03 (1.00, 1.06)	0.042
MELD score	1.10 (1.05, 1.16)	0.001
Phase angle 50 kHz (< 4.9º)	2.05 (1.11, 3.77)	0.021

P values for independent Cox regression models refer to three models explained by age, MELD score, and phase angle. HR: Hazard ratio; MELD: Model for end-stage liver disease.
