Differences between indirect calorimetry variables with versus without CVVHD based on the scenario of indirect calorimetry runs.

Variable	Scenario 1 (N = 32)*	Scenario 2 (N = 45)a	P
Delta REE
kJ/d	36 [−759–450]	−95 [−517–565]	0.69
(kcal/d)	(8.5 [−181–107])	(−23 [−124–135])
Delta RQ	−0.02 [−0.04–0.01]	0.00 [−0.03–0.03]	0.14
Delta VO2 (ml/min)	1.7 [−26.5–15.3]	3.2 [−18.8–19.7]	0.71
Delta VCO2 (ml/min)	−4.8 [−20.0–17.8]	4.5 [−13.2–12.5]	0.39

REE resting energy expenditure, RQ respiratory quotient, VO₂ oxygen consumption, VCO₂ CO₂ production.

^aScenario 1: Indirect calorimetry first with and then without CVVHD; scenario 2: indirect calorimetry first without and then with CVVHD.
