a Elbow graph showing the eigenvalues for the PCA dimensions. The red dashed line indicates the criteria established for selecting the dimensions. b Heatmap showing the contribution values of each AAB for dimensions 1, 2, and 3. Biplots showing PCs 1, 2, and 3. Dimension 1 with dimension 2 (c), dimension 1 with dimension 3 (d) and dimension 2 with dimension 3 (e). The colors gray, dark blue, blue, green and orange represented the groups 0 = no symptoms; 1 = one symptom; 2 = two symptoms; 3 = three symptoms; 4 = four symptoms, respectively.
