GM-CSF and IL-8 concentrations in controls and NE infants over the first week of life.

Cytokine	Control	NE D1	NE D2	NE D3	NE D6–8
GM-CSF (pg/mL)	0.56 (0.08)	0.59 (0.05)	0.62 (0.06)	1.06 (0.17)	0.65 (0.09)
IL8 (pg/mL)	35.86 (7.0)	133.81** (23.3)	137.53** (29.2)	149.07** (30.2)	49.86** (10.1)

Serum concentrations of GM-CSF and IL-8 in NE patients (n = 82) expressed as pg/mL (day 1–7) vs. controls (n = 12) were measured by duplex cytokine analysis in the first week of life. (**p < 0.01 using the Mann–Whitney test).
