Score plot of OPLS-DA. Each point represents a profile of 922 compounds. The value of the predictive component goes on the horizontal axis, and the value of the orthogonal component goes on the vertical axis. This supervised analysis captures 0.836 variation between metabolic profiles (R2Y = 0.836) and exhibits 0.663 predictive power (Q2 = 0.663)
