FDG-PET/CT in intensive care patients with bloodstream infection

Table 5 Logistic regression analyses of factors associated with detecting an infection focus on FDG-PET/CT^a

Parameter	Univariate OR (95% CI)	p
CRP (mg/L)	1.00 (0.99–1.01)	0.55
Leukocyte count (× 10⁹/L)	0.97 (0.91–1.03)	0.29
Duration of ICU stay before FDG-PET/CT (days)	1.03 (0.96–1.11)	0.41
Duration of antibiotic treatment before FDG-PET/CT (days)	1.03 (0.94–1.14)	0.46
Mechanical ventilation during FDG-PET/CT (yes = 1/no = 0)	0.86 (0.26–5.11)	0.86
FDG-PET image quality ((very) poor = 0 / reasonable to good = 1)	0.16 (0.028–0.87)	0.034

^a In the logistic regression analyses, finding a true positive focus of infection was coded as ‘1’ and finding a true negative, false negative or false positive focus was coded as ‘0’
