From: Effect of region of interest on ADC and interobserver variability in thyroid nodules
Interobserver reproducibility of mean ADC measurements (× 10− 3 mm2/s) for all three ROI methods in malignant thyroid nodules. In Bland-Altman plots, the differences in mean ADC measurements (y-axis) were plotted against the mean ADCs (x-axis). Continuous line, mean absolute difference (bias); dashed line, 95% confidence interval of the mean difference (limits of agreement)
