	LOS ED
	β	95% CI		P value
	β	Lower	Upper	P value
Type of cancer—liquid	1.8	−3.58	7.19	0.51
Intravenous fluids in the first 6 hours	3.75	2.44	5.07	<0.0001
Lung	7.37	2.49	12.26	0.003
Temperature	−3.14	−5.74	−0.55	0.02

Imposed: type of cancer (reference: Solid).

Stepwise: age; gender (reference: male); coronaryartery disease; hypertension; diabetes mellitus; COPD; skin; blood; lung; gallbladder; temperature; heart rate; oxygen saturation; WCC; ANC; haemoglobin; BUN; creatinine; bicarbonate; sodium; intravenous fluids in the first 6 hours; intubation in the first 24 hours.

ANC, absolute neutrophil count; BUN, blood urea nitrogen; COPD, Chronic obstructive pulmonary disease; ED, emergency department; LOS, length of stay; WCC, white cell count.
