Urea-to-Albumin Ratio and In-Hospital Mortality in Severe Pneumonia Patients

Table 3

Relationship between UAR level and in-hospital mortality.

In-hospital mortality	UAR >0.2555 group
	HR (95%CI)
Unadjusted	2.788 (1.577–4.929)	<0.001
Model 1	2.724 (1.499–4.949)	0.001
Model 2	2.080 (1.100–3.934)	0.024
Model 3	2.234 (1.146–4.356)	0.018

Reference group is UAR ≤ 0.2555 group. Model 1: age and sex. Model 2: model 1 plus treatment (mechanical ventilation, CRRT, and vasopressor use). Model 3: model 2 plus and laboratory test (creatinine, ALT, and AST). CRRT, continuous renal replacement treatment; ALT, alanine aminotransferase; AST, aspartate aminotransferase; HR, hazard ratio; CI, confidence interval.
