Table 5.

Pairwise comparison of AUCs of different severity assessment methods for predicting 30-day mortality in HAP patients.

Assessment models	PSI	CURB-65	SOFA	APACHE II
CURB-65	0.115 (1.577)
SOFA	0.312 (1.010)	0.010 (2.589)
APACHE II	0.209 (1.255)	0.002 (3.055)	0.801 (0.252)
qSOFA	0.407 (0.829)	0.590 (0.539)	0.030 (2.170)	0.003 (3.017)

Data were presented as P values (Z values). AUC: Area under the curve; HAP: Hospital-acquired pneumonia; PSI: Pneumonia severity index; CURB-65: Consciousness, urea nitrogen, respiratory rate, blood pressure, and age ≥65 years; SOFA: Sequential Organ Failure Assessment; APACHE II: Acute Physiology and Chronic Health Evaluation II; qSOFA: Quick Sequential Organ Failure Assessment.
