Systemic inflammatory parameters of the patients from the prospective cohort

Parameter	Confirmed VRI (n = 12)	suspected VRI (n = 66)	p value (MWU-test/χ2)
Plasma CRP (mg/dl)	92 (53–278.3)	120 (66.3–189.3)	0.857
Plasma PCT (yg/l)	0.08 (0.07–0.15)	0.14 (0.07–0.4)	0.129

Data are expressed as mean ± standard deviation, or median and interquartile range, as appropriate. On the right side of the table are presented the comparisons of the systemic inflammatory parameters between the different groups
