Bland & Altman graph with limits of agreement (LOA). The differences between test sessions 1 and 2 (test 2 minus test 1) plotted against their mean for each subject for TE20 (degrees) in 24 uninjured subjects, together with the 95% confidence interval (CI) and the 95% LOA. In this figure, the differences are generally increasing with their means (heteroscedasticity). Note: several subjects have the same value.
