Serum neutrophil gelatinase-associated lipocalin at inception of renal replacement therapy predicts survival in critically ill patients with acute kidney injury

Table 2 Outcomes at day 28 after initiation of RRT

Variable	Total	non-SIRS/sepsis	SIRS	Sepsis	Pvalue
Mortality (n;%)	41 (37.6)	6 (24.9)	15 (28.3)	20 (64.5)	0.001
VFDs (mean ± SD)	7.4 ± 10.3	5.5 ± 9.5	8.3 ± 10.7	7.2 ± 10.1	0.580
ICU-free days^† (mean ± SD)	5.2 ± 8.4	4.6 ± 8.3	5.4 ± 8.4	5.4 ± 8.8	0.738
Renal recovery^‡ (n;%)	45 (66.2)	13 (68.4)	26 (68.4)	6 (54.5)	0.673

ICU = intensive care unit; SD = standard deviation; SIRS = systemic inflammatory response syndrome; VFDs = ventilator-free days (defined as the number of days between successful weaning from mechanical ventilation and day 28 after study enrollment).
† ICU-free days were defined as the number of days between successful transfer to a normal ward and day 28 after study enrollment; ‡ Renal recovery was defined as no need for RRT at day 28 after study enrollment.
