Bland‐Altman plots illustrating level of agreement between ActiGraph and Fitbit. (A) Steps, (B) LPA, (C) MPA, (D) VPA, (E) MVPA. LPA, low intensity physical activity; MPA, moderate intensity physical activity; MVPA, moderate and vigorous intensity physical activity; VPA, vigorous intensity physical activity. Legend: The dotted lines show the mean of the differences between devices, the dashed lines show 95% limits of agreement (±1.96 SD) and the solid black lines show the estimated linear regression lines. b = slope of the estimated regression line. The p‐values show whether the regression slopes are significantly different from zero. Positive values indicate an underestimation by the Fitbit as compared to ActiGraph, and negative values indicate an overestimation
