Bland-Altman plot showing cross-sectional (CS readers’ mean) vs. projectional (PJ readers’ mean) imaging interreader agreement (N = 107). Graphical display of the means against their respective paired differences. The Bland-Altman limits of agreement (upper/lower dashed lines) are displayed with their respective 95% confidence intervals. The mean of the differences (bias) is displayed as the central dashed line with the respective 95% confidence intervals. The zero y is the reference line of perfect average agreement.
