Discrimination between SMA and DMD patients. PCA/CA classification and MCCV showed clear discrimination between the SMA group and the DMD group. PCA/CA was performed on 1,000 variables from 0.5 to 10 ppm (exclusion: see Materials and Methods) with Expl. Variance of 99.9%. The Confusion Matrix is the result of 100 Monte-Carlo-Runs (MC) with 15-fold CrossValidation (CV). Space of discrimination is one representation of the modelling samples in 2-dimensions. □ represent the model-set and represent the test-set. SMA: spinal muscular atrophy. DMD: Duchenne muscular dystrophy
