Scores plot, cross validation and a permutation test of PLS-DA model for CTRL, NSCLC and MWA groups. CTRL, healthy controls (n = 43). NSCLC, nonsmall-cell lung cancer patients (n = 38). MWA, microwave ablation treated patients (n = 38). The values of R2 (0.68) and Q2 (0.45) revealed satisfactory goodness of fit and goodness of prediction, respectively. The nominal P value (0.036) of the permutation test was less than 0.05, confirming the validity of the PLS-DA model at a 95% confidence level
