From: Calorie intake and patient outcomes in severe acute kidney injury: findings from The Randomized Evaluation of Normal vs. Augmented Level of Replacement Therapy (RENAL) study trial

Variable name Effect (discrete variable) Odds ratio CI (95%) P-value
Median daily calorie intake during ICU admission High versus low 1.079 0.55 2.13 0.8275
Mean daily calorie intake during ICU admission (per 100 Kcal change)   0.953 0.91 1.00 0.0636
Mean fluid balance (input-output) (litre)   2.016 1.61 2.53 <.0001
Patient's age   1.037 1.03 1.05 <.0001
Patient's weight (Kg)   0.989 0.98 1.00 0.0394
Time from ICU admission to randomization (days)   1.002 1.00 1.00 0.0047
SOFA liver (score) Failure versus normal 3.384 1.55 7.38 0.0022
International normalized ratio   1.200 1.03 1.39 0.0172
Hemoglobin (g/L)   0.992 0.98 1.00 0.0353
Albumin (g/L)   0.977 0.96 1.00 0.0300
PaCO2 (mm/Hg)   1.016 1.00 1.03 0.0249
