Fig. 2From: 1H-NMR-based metabolic profiling identifies non-invasive diagnostic and predictive urinary fingerprints in 5q spinal muscular atrophyDiscrimination between SMA patients and healthy controls. PCA/CA classification and MCCV showed clear discrimination between the SMA group and an age-matched healthy control 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 24-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.
