Figure E1: Bland-Altman plots for interrater agreement for DW imaging (DWI) findings according to study group. There was good agreement, without a significant difference between the two groups, for A, group 1 (mean difference, 1.8 mL; limits of agreement: 6.8, 10.4 mL) and B, group 2 (mean difference, 1.2 mL; limits of agreement: 4.8, 7.1 mL). Dotted line = line of equality.
