Method Abstract 3rd paragraph:"A new approach was developed to evaluate the K(i) 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.1373 right column bottom paragraph:"The stepwise univariate analysis method was used to calculate the 95% CIs for each Ki value of the organs and tissues for all subjects (Table 4). As shown in Figure 2, Elia's Ki values were within but close to the right boundary of 95% CIs for the 7 organs and tissues." P.1374 left column bottom paragraph:"The stepwise univariate analysis method was used to calculate the 95% CIs of Ki values for the 3 age groups (Table 4). For the young and middle-age adults, Elia’s Ki values were located within the 95% CIs for the 7 organs and tissues. For the >50-y group, however, Elia’s Ki values were outside the right boundary of 95% CIs for the 7 organs and tissues (Figure 4). This observation indicated that Elia’s study overestimated Ki values in the adults aged >50 y." See notes beneath table
