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

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
  1. 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).
  2. † 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.
