Fig. 1.

Box and whisker plot of contouring times, dice similarity coefficient (DSC) and distance to agreement (DTA) for prostate structures from 3 centres using manual and deep learning contouring (DLC). The boxes indicate the interquartile range (IQR), the line indicates the median and the cross indicates the mean. The whiskers indicate the highest and lowest values within 1.5 times the IQR and data outside this range indicated by circles. Axes for DTA and DSC have been limited to exclude one centre 2 patient left femoral head result as the DLC contour was outside of the external volume.
