Graphical presentation of comparison of two measurements of the left and right jugular foramina in Bland-Altman plots. The reproducibility of two segmentation processes is demonstrated. The differences between the two measurements (red dots) are plotted against the averages of the differences. Dotted lines indicate the lower and upper limits of agreement (mean difference ± 2x standard deviations). 95% of all differences are within two standard deviations, representing excellent reproducibility. Outliers are marked with a black rim.
