Table 3.
Statistics of the Bland-Altman analysis results for 25 participants. Each column, from left to right, is task, mean test-retest difference or bias (
) and its p value, standard deviation of the differences (s), 95% confidence interval (CI) of 
, 95% CI of limits of agreement (LoA), slope of the best fit line and its p value, and coefficient of repeatability (COR = 1.96×s)
