Boxplot showing radiomic features in S50p and S25p images normalised to full-count images. On the left is an example of a feature with low noise-induced variability and bias (ICC and SDM ≥ 0.9 for both S50p and S25p) illustrated by the narrow width of the box centred around the dotted line of unity, respectively. On the right is an example of a feature with high noise-induced variability and bias (ICC = 0.85 and 0.69, SDM = 0.85 and 0.49 for S50p and S25p, respectively) illustrated by the increase in the width of the box and the shift of the median from the line of unity in S25p, respectively
