On the left side of the table, data reports the number of activities that were inside the ± 20% Critical Margin of agreement in the Bland-Altman Plots. On the right side, difference between measure (TM) and estimate (M) of active time are presented according to this formula: [(M-TM)/((TM+M)/2)*100]. Paired Sample T Test were used to evaluate the differences of agreement of both M3 and M1 with TM. Values are presented as mean ± SD.
