  1. Mean values of energy expenditure (EE) measured by Sensewear Pro3 (SWA) and indirect calorimetry (IC) and absolute and relative bias between units1. Positive bias values indicate overestimation of SWA.
  2. 1Values are x ¯ with 95% confidence interval.
  3. 2Regarded as non conclusive due do short time period (see text).
