Serum vascular endothelial growth factor affects tissue fluid accumulation and is associated with deteriorating tissue perfusion and oxygenation in severe sepsis: a prospective observational study

Table 4 Correlation coefficients between urine output, administrated fluid, serum VEGF, and serum albumin

Measures	I/O	UO	IV	VEGF	Albumin
I/O^a	1
UO^a	− 0.390^b	1
IVF^a	0.544^b	− 0.043	1
VEGF	0.093	0.011	− 0.033	1
Albumin	0.107	− 0.143	0.052	− 0.401^b	1

Numbers in cells are Pearson’s r or Spearman’s rho correlation coefficients. Vascular endothelial growth factor, VEGF; I/O: intake and output; UO: urine output; IVF: intravascular fluid. ^aData recorded on the day before the near-infrared spectroscopy measurements. ^bp < 0.01. The actual p values have been included in Additional file 1
