Figures & Tables

Bland-Altman plots for the test-retest reliability. Each plot illustrates the agreement between time 1 and time 2 measurements and identifies possible outliers. Each participant is represented on the graph with the mean value of the two assessments (x-axis) and difference between the assessments (y-axis). Reference lines show the mean difference between time 1 and time 2 (solid line), and 95% limits of agreement for the mean difference (dotted lines).
