Increased Serum Concentrations of TNF-Like Weak Inducer of Apoptosis Predict Higher 28-Day Mortality in Patients with Sepsis

Table 3

Correlation of TWEAK concentrations and other biomarkers.

Biomarkers	TWEAK concentrations		ΔTWEAK concentrations
	r	p	r	p
Lactate	0.032	0.782	-0.176	0.122
CRP	0.129	0.257	-0.227	0.044
Procalcitonin	0.152	0.183	-0.242	0.031
NT-proBNP	0.082	0.475	0.052	0.647

r, Spearman correlation coefficient. CRP, C-reactive protein. NT-proBNP, N-terminal pro-B-type natriuretic peptide. TWEAK, Tumor Necrosis Factor Weak Inducer of Apoptosis.
ΔTWEAK concentrations refer to dynamic changes of TWEAK concentrations between 1st day and 3rd day of admission to ICU.
