Cross-validated score line plot for serum and extracellular compartment from tumor. The score line plots are based on the final OPLS-DA models from each study. The serum scores is shown by the black line and scores from the tumor extracellular compartment is shown by the grey line. The x-axis consists of the eight patients that was included in the previous microdialysis study and this study regarding serum samples. The serum OPLS-DA model consisted of 1 predicted and 1 orthogonal component and predicted 31.9 % of the response variation (Q2 = 0.319). The tumor OPLS-DA model consisted of 1 predicted and 1 orthogonal component and predicted 35.5 % of the response variation (Q2 = 0.355). The p-value based on ANOVA on the cross-validated OPLS-DA model is 0.006 for the serum model and 0.005 for the tumor model
