The supervised orthogonal partial least-squares discriminant analysis (OPLS-DA) shows the best possible discrimination between nonsurvivors and survivors of H1N1 infection. a OPLS-DA plot for proton nuclear magnetic resonance data (R 2 = 0.831, Q 2 = 0.597, P = 0.004). b OPLS-DA plot for gas chromatography-mass spectrometry data (R 2 = 0.909, Q 2 = 0.829, P = 0.0001). The x-axis represents the prediction component that shows differences between groups, and the y-axis represents the orthogonal component differences within the group. R 2 represents goodness of fit, Q2 represents goodness of prediction, and P value shows the significance level of the model (x-axis = predictive components, y-axis = orthogonal component)
