TABLE 1. Average Mean of the Differences (
), Coefficient of Repeatability (RPC), Upper Limit of Agreement (Upper LA), Lower Limit of Agreement (Lower LA), Linear Regression Analysis (r2, m, b), Mean Absolute Error (MAE), and Root Mean Square Error (RMSE) Across Participants for Time Point One (T1) and Two (T2). Shaded Area Indicates That Values From Comparisons are the Same Between Raw and Zeroed Values.
