Multivariate logistic regression analysis of factors associated with the presence of signs for a suspected cause of fever on CT images

Factors	Odds ratio	95% CI	p
Use of contrast agents in CT	0.88	0.43–1.79	0.72
qSOFA score ≥ 2	1.57	0.66–3.72	0.30
CRP	1.04	0.98–1.1	0.21
Presence of immunocompromised conditionsa	0.96	0.47–1.96	0.91
Presence of an attending physicians’ estimation regarding a cause of the fever before the CT scanb	4.99	2.31–10.76	0.00
