Race
Black vs White	1.23 (0.97, 1.56)
Asian vs White	1.79 (1.30, 2.45)**
Other vs White	1.25 (0.99, 1.57)
Unknown vs White	0.92 (0.56, 1.50)
Comorbidity Index	1.07 (1.04, 1.10)*
Admission from (facility vs home)	1.05 (0.84, 1.30)
MEWS (scores > 4, severely ill, vs scores 1–4)	5.42 (4.51, 6.51)*
First documented oxygen delivery
Nasal cannula vs none	2.50 (1.95, 3.21)*

Mechanical ventilation vs none	13.21 (8.17, 21.35)*
DNR
No DNR at all vs late DNR	0.09 (0.07, 0.11)*
Early DNR vs late DNR	0.91 (0.65, 1.29)

Notes: CI = confidence interval; Comorbidity Index = Charlson Comorbidity Index (without age component); DNR = Do-Not-Resuscitate; MEWS = Modified Early Warning Score; OR = odds ratio.
