Lactate and Bilirubin Index: A New Indicator to Predict Critically Ill Cirrhotic Patients’ Prognosis

Table 3

Multivariate regression results of 28-day mortality for critically ill patients with cirrhosis.

Parameter	OR	95% CI		value
		Lower	Upper
Age (years)	1.034	1.012	1.057	0.002
Length of ICU stay (days)	0.860	0.785	0.942	0.001
Mechanical ventilation duration (hours)	1.006	1.002	1.010	0.005
BUN (mg/dL)	1.015	1.005	1.025	0.002
PTT (seconds)	1.032	1.017	1.048	<0.001
Respiratory rate	1.069	1.015	1.127	0.012
LB index	5.487	3.542	8.501	<0.001

ORs and values were estimated using multivariate logistic regression. Age, sex, length of ICU stay, and variables were statistically significant in the tests and were included in the multivariate analysis. OR: odds ratio; CI: confidence interval; ICU: intensive care unit; BUN: blood urea nitrogen; PTT: partial thromboplastin time; LB: lactate and bilirubin.
