Comparison of NGAL, creatinine, and BNP according to the sepsis diagnosis

	Clinical sepsis (n = 119)		PCT-based sepsis (n = 150)
	Non-sepsis (n = 221)	Sepsis (n = 119)	Non-sepsis (n = 190)	Sepsis (n = 150)
BNP (pg/mL)	72.3 (52.8 – 115.7)	140 (65.5 – 189.3)	66.7 (30.8 – 96.0)	146.5 (93.5 – 223.4)*
NGAL (ng/mL)	184 (161.9 – 233.6)	210 (137.0 – 265.0)	137 (115.0 – 167.0)	333 (255.6 – 448.0)†
Creatinine (mg/dL)	0.94 (0.85 – 1.09)	0.84 (0.71 – 1.10)	0.81 (0.76 – 0.93)	1.12 (0.98 – 1.50)†

^*P = 0.0001 vs. non-sepsis.

^†P < 0.0001 vs. non-sepsis.

Data are expressed as median (95% confidence interval).

BNP: B-type natriuretic peptide; NGAL: neutrophil gelatinase-associated lipocalin; PCT: procalcitonin.
