Table 3.

The characteristics of the LiTS training and test sets. The median values and the interquartile range (IQR) are shown for each parameter. In addition, P-values were obtained by Mann–Whitney u test, describing the significance between the training set and test set shown in the last column. An alpha level of 0.05 was chosen to determine significance.
