Table 6.

The median and interquartial range of C-reactive protein, C-reactive protein velocity and procalcitonin for the bacterial and non-bacterial groups in a subgroup of 48 patients

	Non-bacterial (n = 17)		Bacterial (n = 31)		P value
	Median	Interquartile range	Median	Interquartile range
PCT (ng/ml)	0.05	0.05 to 0.24	0.21	0.05 to 0.53	0.025
CRP (mg/L)	29.0	15.5 to 52.1	99.9	41.3 to 143.7	< 0.001
CRPv (mg/L/hour)	0.44	0.26 to 1.32	2.67	1.39 to 5.16	< 0.001

CRP = C-reactive protein; CRPv = C-reactive protein velocity; PCT = procalcitonin.
