Bland–Altman plot and scatter plot assessing interobserver pairwise agreement for image quality ratings. (a) Bland‒Altman plot. The x-axis represents the mean values, and the y-axis represents the difference between the two. The red dashed line shows the mean bias, and the dashed lines show the 95% CI based on the standard deviation of the distribution. (b) Scatter plot. The x-axis represents the ratings from observer 1, and the y-axis represents the ratings from observer 2
