Table 4.
(A) Principal component analysis of three groups of female mice [all females, wildtype (WT) females only, and knockout (KO) females only]. For each group there were 21 principal components (PCs), but only those given below satisfied the first criterion of λ2 > 1. Significant eigenvalues, marked as bolded numbers with asterisks, satisfied the second and third criterion. Other eigenvalues that shared similarities to significant eigenvalues in other groups are marked with a tilde (∼). Both marked eigenvalues correspond to PCs that were considered in later analyses. (B) Rotated component matrix for groups of female mice with significant PCs derived from the principal component analysis displayed in Table 4. The columns below are the significant PCs; there were no insignificant PCs of shared similarity. The coefficient value for each PC is given after VARIMAX rotation.
