APACHE II (per 1 point) 1.09 1.06 to 1.13 1.06 to 1.12 <0.001
Day of pneumonia onset peak T, C (per 0.1 degree) 0.76 0.63 to 0.92 0.65 to 0.89 0.004
ICU prior to pneumonia 0.29 0.14 to 0.61 0.16 to 0.54 0.001
AUROC = 0.750
Hosmer-Lemeshow goodness-of-fit p = 0.910
 -Factors included but not retained at the p value of < 0.1:
Age, BMI, CAP/HCAP, day of pneumonia onset peak WBC, peak WBC over 7 days after pneumonia onset, CrCl > 50
 -Factors excluded for perfect prediction:
ICU transfer after pneumonia onset, no ICU during pneumonia admission
 -Factors excluded for collinearity:
Charlson, pre-pneumonia LOS, ICU at onset of pneumonia
