A. Prediction results derived from the OPLS-DA model corresponding to the comparison between healthy individuals and NSCLC patients (training set). B. OPLS-DA score plot displaying the prediction of the samples included in the validation set based on the model corresponding to the training set (: healthy individuals -validation set-; : NSCLC patients -validation set-; : BPD patients -validation set-; : healthy individuals -training set-; : NSCLC patients -training set-). C. Misclassification table based on the logistic regression equation. D. Boxplot (log scale) representing the intensities of the metabolites included in the logistic regression equation for the different groups. For each box, the central line is the median, the edges of the box are the upper and lower quartiles, the whiskers extend the box by a further ±1.5 interquartile range (IQR), and outliers are plotted as individual points.
