Figure 4.

3D Scatter plot of all 20 unknown (new and different) subjects [10 R/LTS (green) and 10 NR/STS (purple)] used in the Validation Study in connection with the F₁, F₂, and F₃ prognostic biomarker models. The F₁, F₂, and F₃ scores of all 20 unknown subjects are plotted against each other (F₁ vs. F₂ vs. F₃). As can be seen, there are two distinct, separate clusters: the green one (R/LTS group) is at the front and at a lower level, whereas the purple one (NR/STS group) is at the back and at a higher level. It can also be seen that there were no misclassifications.
