Feature reduction was performed by PCA. (a) Variance against the number of dimensions in the result of PCA. (b) Individual case in the PCA. Each individual case is plotted on the platform of dimension 1 (Dim1) and dimension 2 (Dim2). Dim1 and Dim2 contribute to the principal component with proportions of 42.1% and 19.1%, respectively. (c) Individual case in the PCA with different groups. Group 0 [BI(-)] in red and group 1 [BI(+)] in green are plotted in the platform of dimension 1 (Dim1) and dimension 2 (Dim2).
