Fig. 2.

Average estimated TEE (kcal/h) as percentage of the reference; overall and per activity cluster. Boxplot of the cumulative TEE of the entire lab protocol with jittered raw data points from participants’ individual cumulative TEE as percentage of reference TEE (left-hand panel; with mean and standard error in blue) and (right-hand panel) per activity cluster (without raw data points and plusses for outliers; mean and standard error in blue). Dashed horizontal black lines indicate the 90% confidence interval around the averaged cumulative TEE ratio. Solid pink horizontal lines reflect the 90–111% limits and the red lines reflect the conventional 80–125% limits of equivalence. In the right-hand panel, in the x-axis labeling, a suffix “i” concerns indoor activities at a fixed pace on the treadmill or ergometer; the “o” suffix concerns data from outdoor activities that were self-paced
