Method 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)."
Comments P.1372 right column bottom paragraph:"The masses of 4 high metabolic rate organs (ie, liver, brain, heart, and kidneys) and 3 low metabolic rate tissues (ie, skeletal muscle, adipose tissue, and residual mass) for all subjects and 3 age groups are presented in Table 3. No significant differences in liver, brain, heart, skeletal muscle, and adipose tissue mass were observed between the 3 groups (both ANOVA and pairwise comparisons with Bonferroni adjustment, all P>0.1)."
