The Accuracy of APUA Model, Serum Albumin Alone, CURB-65 and PSI Class for Evaluating the Risk of in-Hospital Mortality in Community-Acquired Pneumonia Patients with Type 2 Diabetes

Variables	AUC (95% CI)	SE	P	P*	P#
Training set (N=359)
APUA model	0.814(0.770~0.853)	0.034	<0.001
Albumin	0.695(0.645~0.743)	0.037	<0.001	<0.001
CURB-65	0.686(0.635~0.733)	0.045	<0.001	0.002	0.864
PSI class	0.710(0.661~0.757)	0.044	<0.001	0.020	0.804
Validation set (N=172)
APUA model	0.796(0.728~0.854)	0.076	<0.001
Albumin	0.710(0.636~0.777)	0.072	0.003	0.232
CURB-65	0.655(0.578~0.725)	0.086	0.073	0.067	0.645
PSI class	0.727(0.654~0.792)	0.057	<0.001	0.343	0.870

Notes: *Compared with APUA model, ^#Compared with Albumin alone.

Abbreviations: AUC, area under curve; CI, confidence interval; SE, standard error; PSI, pneumonia severity index.
