Fig 1From: Can calculation of energy expenditure based on CO2 measurements replace indirect calorimetry?Correlation and limits of agreement between calculated energy expenditure based on CO2 measurements (EEVCO2) and energy expenditure (EE) measured by indirect calorimetry. a EEVCO2_0.85 vs. measured EE. b EEVCO2_FQ vs. measured EE. Solid lines indicate the bias and fine dotted lines indicate the limits of agreement in the Bland-Altman plots. EEVCO 2 _0.85 EEVCO2 calculated from CO2 consumption (VCO2) and assumed respiratory quotient (RQ) of 0.85, EEVCO 2 _FQ EEVCO2 calculated from VCO2 and assuming RQ as food quotient (FQ)Back to article page
