Elevated Blood Urea Nitrogen-to-Serum Albumin Ratio as a Factor That Negatively Affects the Mortality of Patients with Hospital-Acquired Pneumonia

Figure 3

Kaplan–Meier curves of 30-day survival in HAP patients stratified by BUN/ALB. A high BUN/ALB was significantly associated with a worse survival than a low BUN/ALB (). HAP: hospital-acquired pneumonia; BUN/ALB: blood urea nitrogen/blood albumin.
