Data are presented as mean differences, 95% confident interval (CI), and standard deviation (SD) as well as limits of agreement (LOA), mean absolute percent error (MAPE), and Lin's concordance correlation coefficient (LCCC). Cut‐points expressed with the acceleration metric used; Evenson et al. 11 , Hildebrand et al. 13 , 14 , and Butte et al. 10 .
Abbreviations: ENMO, Euclidean norm −1 g; MVPA, Moderate‐to‐vigorous physical activity; VACounts, Vertical axis counts; VMCounts, Vector magnitude counts.
