Figure 2.

Bland-Altman plot of MVPA (min/d) for vertical axis and vector magnitude. Note: Solid line is mean bias and dashed lines are 95% limits of agreement. MVPA is defined as time during which the accelerometer registers vertical cpm > = 1952 [12] and VM cpm > = 2691 [22]. Monitor-wear time was estimated using Limited-log + Choi [10, 19].
