Figure 2: Discriminant Weighting Plot of Methods 1, 2 and 3. The plot shows discriminating peaks between DMD and control samples based on weighting coefficients (labeled as loading on y axis). The positive and negative weightings coefficient values observed in Figure 2a, 2b and 2c indicate whether these peptides are increased or decreased in the DMD samples compared to the controls. Peaks with negative weightings coefficients indicate higher intensities for DMD samples compared to controls, whereas peaks with positive weightings coefficients indicate higher intensities in controls compared to DMD samples
