Multivariable adjusted competing risk regression model for mortality

Variables	HR (95% CI)	P value
Age, years	1.98 (1.71 to 2.31)	<0.001
Neutrophils ×109/L, percentage	1.71 (1.27 to 2.31)	<0.001
Lactate dehydrogenase, IU/L	1.31 (1.15 to 1.49)	<0.001
Respiratory rate, breaths/min	1.31 (1.15 to 1.49)	<0.001
Glasgow Coma Scale	0.70 (0.63 to 0.78)	<0.001
Oxygen saturation (SpO2)	0.82 (0.74 to 0.91)	<0.001
Creatinine, µmol/L	1.19 (1.11 to 1.28)	<0.001

The predictors were scaled using z-score transformation, and HRs should be interpreted as 1 SD change in the values of the parameters.

SpO₂, peripheral capillary oxygen saturation.
