Figure 6 Data for IE measurements and intraobserver agreement. A: Scatterplot of blood flow measurements (dB) shows data for second time (x-axis) and first time (y-axis) measurement of observer 1; line of perfect agreement is shown; B: Agreement plot for IE measurements made by 2 measurements of observer 1. Plots the difference between 2 measurements and mean measurements. Top and bottom lines show the 95% limits of agreement; middle line shows mean difference.
