Table 2 Energy expenditure (EE) estimates from three devices compared with indirect calorimetry (IC) in the optimization cohort 1. Mean absolute percentages error (MAPE) percentages, paired sample t test statistics and intraclass correlation (ICC) statistics with 95% CI presented for each device for total 20 min of testing. *Shows statistical significance.
