3D Scatterplot shows the partial separation between the two groups, DKA (red) and non-DKA (black), for the 3 best separating components of neurochemical data from Day 28 (or should it be 6 months?). 80% prediction ellipses are plotted in the same colour scheme.        The plots show 3 components - need to say how much variance was explained by each component to justify the statement that only one PLS component described the data.
