Development of a Portable Respiratory Gas Analyzer for Measuring Indirect Resting Energy Expenditure (REE)

Figure 7

Clinical trial results. (a∼d) show the correlation plot of VCO₂ (R = 0.86), VO₂ (R = 0.83), RQ (R = 0.48), and REE (R = 0.86) between the developed device and Vmax 29, respectively. (e∼h) show Bland and Altman plots of VCO₂, VO₂, RQ, and REE, respectively.
