Figure 2.
Bland-Altman plots for agreement between REE values derived from indirect calorimetry
(IC: Deltatrac®) and REE values derived a) from Servo-I® measurements, b) from the Schofield-weight
equation, c) from the Schofield-weight/height equation and d) from theWHO equation. The mean relative
difference is represented by the solid horizontal line; dotted lines indicate 95% limits of agreement

. Accuracy and inaccuracy quantified by the proportions of measurements with a relative
difference ≤10% and >30% when comparing REE derived from Servo-I® and predictive equations with
indirect calorimetry derived REE in children ≥15 kg
