||Abstract 3rd paragraph:"A new approach was developed to evaluate the K(i) [specific metabolic rate] values of major organs and tissues on the basis of a mechanistic model: REE = Σ(K(i) × T(i)), where REE is whole-body resting energy expenditure measured by indirect calorimetry, and T(i) is the mass of individual organs and tissues measured by magnetic resonance imaging. With measured REE and T(i), marginal 95% CIs for K(i) values were calculated by stepwise univariate regression analysis. An existing database of nonobese, healthy adults [n = 131 body mass index (in kg/m²) <30] was divided into 3 age groups: 21-30 y (young, n = 43), 31-50 y (middle-age, n = 51), and > 50 y (n = 37)."
||P.1375 left column 2nd & 3rd paragraphs: "Another approach has been applied to evaluate the applicability of Elia's Ki values that compares REEp [predicted
REE] with REEm [measured REE] (primary source 8). The predicted REE is calculated by Equation 3 with the Ki values suggested by Elia. If the REEm – REEp difference is close to zero, [investigators] may consider that Elia's Ki values should be applicable as a whole. This approach is dependent on simultaneous measurements of REE and organs and tissues from the same subjects. Currently, only 2 laboratories have measured REE and organs and tissues using magnetic resonance imaging: Christian-Albrechts University, Kiel, Germany and St Luke's–Roosevelt Hospital, Columbia University, New York, NY (primary source 8, refs 23, 24). The REEm – REEp differences reported in the previous and present studies are summarized in Table 6."
