Table 4 Univariate analysis of continuous factors associated with death at 1 year among sARF patients

From: Prognosis for long-term survival and renal recovery in critically ill patients with severe acute renal failure: a population-based study

Factor Alive (n = 87) Dead (n = 153) p value
Median age (IQR; years) 62.5 (48–72) 71 (59–79) <0.0001
Mean Charlson co-morbidity index score (±SD) 5.3 (± 3.6) 6.7 (± 3.5) 0.002
Mean APACHE II score (± SD) 30.3 (± 8.5) 34.8 (± 8.3) 0.0001
Median pre-dialysis creatinine (μmol/l) (IQR) 470 (341–582) 344 (250–475) 0.0001
Median pre-dialysis platelets (×109/l; IQR) 156 (71–241) 83 (41–170) 0.0001
