Prediction Bias and Accuracy of Established Resting Energy Expenditure Equations

	Prediction Bias	±2 SD LOA	Accurate	Overpredicted	Underpredicted
Indirect Calorimetry	—	—	—	—	—
Harris-Benedict	35.8	491.4	53.5%	19.4%	27.1%
Mifflin	548.5	489.2	43.1%	12.5%	44.4%
Owens	41.2	520.3	50.7%	21.5%	27.8%
WHO/FAU/UNU	-26.7	496.3	59.0%	25.0%	16.0%
SECA	40.3	537.4	49.6%	20.9%	29.5%

Overpredicted resting metabolic rate values were defined as 10% of the value obtained from indirect calorimetry. Underpredicted resting metabolic rate values were defined as 10% of the value obtained from indirect calorimetry

Abbreviations: LOA – limits of agreement; SD – standard deviation; WHO – World Health Organization; FAU – Food and Agriculture Organization of the United Nations; UNU – United Nations University
