Detection of infection within the first 48 hours

	Non-infected	Infected	P-value
IG# (cells/μl)	427.6 ± 1376.2	630.5 ± 1042.5	<0.0001***
CRP (mg/l)	132.1 ± 73.6	170.5 ± 104.3	0.077
LBP (μg/ml)	61.9 ± 44.3	81.8 ± 46.9	0.048*
IL-6 (ng/l)	457.2 ± 691.7	1789.9 ± 9514.0	0.011*
SOFA (95% CI)	9.1 (8.2 – 9.9)	7.9 (7.3 – 8.5)	0.024*

Clinical parameters of patients with or without infection were determined and the P-value between these two groups was calculated using Student’s t test (CRP, LBP and SOFA) or Mann–Whitney U-test (IG# and IL 6); P < 0.05*; P < 0.005**; P < 0.0005*** (n = 70). Data are given as mean ± SD or mean score value (SOFA). IG#, immature granulocyte count; CRP, C-reactive protein; LBP, lipopolysaccharide binding protein; IL 6, interleukin-6; SOFA, sequential organ failure assessment score.
