PCA identifies difference in hindlimb gait dynamics. Principal component analysis of the Digigait gait performance of left, right, fore, and hindlimbs in female (A) and male (B) control-GFP (blue) and GR50-GFP (red) mice at 12 months old. n = 4 mice per sex and genotype. Ellipses indicate spread of variance. Size of dot representing each mouse defines its overall contribution to the spread of the variance. Arrows list top 10 Digigait measurements, or indices, that contribute to the principal component space. The color of each arrow is scaled according to the indices’ contribution to the first two dimensions of the principal component space (Contrib. purple-orange scale).
