TTGE profiles FDA model. Factorial discriminant analysis (FDA) plot for TTGE profiles from CD patients studied, during both active (○) and inactive (◊) celiac disease, and controls (□). The percentages of variation described by the factorial axes (F1,F2) are shown in the parentheses. Center of gravity for each group is reported as filled symbol. Mahalanobis distances (D²), between the three centers of gravity were: active vs inactive = 93.030; active vs control = 551.840; inactive vs control = 290.021. Comparison of the aforementioned distances was statistically significant (Mann-Whitney and Wilcoxon tests, P < 0.0001) between the three groups of patients. The predictability of the model is 100%.
