Predictive equations over-estimate the resting energy expenditure in amyotrophic lateral sclerosis patients who are dependent on invasive ventilation support

Table 3 Comparison of the values for measured (mREE) and predictive (pREE) resting energy expenditure in five patients having severe amyotrophic lateral sclerosis.

Equation	mREE (kcal/d)	pREE (kcal/d)	Difference between medians (95% confidence interval of the difference)
Harris Benedict [24]	1060 (960-1480)	1580 (1190-2020)	585* (425-760)
WHO/FAO/UNU [25]	1060 (960-1480)	1656 (1374-2039)	590* (472-780)
Mifflin-St Jeor [28]	1060 (960-1480)	1557 (1399-1909)	538* (439-688)
Owen [26, 27]	1060 (960-1480)	1726 (1183-1879)	566* (414-691)
Fleisch [29]	1060 (960-1480)	1630 (1210-1938)	567* (417-727)

REE was measured by the use of indirect calorimetry on 13 occasions.
Values are median (range) or difference between medians (95% confidence interval of the difference). *P < 0.01 (Wilcoxon signed ranks test)
