Fig. 1.

Plot of differences in the ICP values from $t_{\mathrm{pre}}$ and $t_{\mathrm{post}}$ (x-axis) against ICP values (y-axis). Squares represent the values for $t_{\mathrm{pre}}$, while rhombuses represent the values from $t_{\mathrm{post}}$. Patients can be separated into 4 classes based on the difference and the ICP values from $t_{\mathrm{pre}}$, i.e. Class_1 = [low diff, low ICP1] (green region), Class_2 = [high diff, low ICP1] (red region), Class_3 = [low diff, high ICP1] (yellow region), and Class_4 = [high diff, high ICP1] (blue region).
