Figure 4:

In (a), estimated rate of energy expenditure (EE) from the Tritrac-R3D monitor vs. EE measured by the AEMS during one study period (representative data from the female PWS participant, PWSf, age 35, weight 54.4 kg). Data points below the line of identity represent underestimation. In (b), estimated total energy expenditure (EE) for the 8 hours from the Tritrac-R3D monitor and the two compartment power model (Equation 3 of Methods) vs. total EE measured by the AEMS for each participant is shown. Data points below the line of identity represent underestimation.
