Figure 6
Molecular ions of importance for prediction outcome. Plot displaying the 50 ions of largest importance for the classification outcome as specified by the coefficients of the logistic regression model. Negative coefficients suggest upregulation in the tumor regions and positive coefficients suggest higher intensity in the non-tumor regions (i.e. downregulation in the tumor regions). The coefficients are sorted according to m/z value and the lipid-range is highlighted by the red box.
