Results from a repeated measures analysis of variance on digit ratio.

Within subject factors were front vs. rear and left vs. right. Between strain effects account for approximately 36% of between subjects variance, while sex and sex-by-strain effects contributions are not meaningful (nm). Within-subjects effects significant at the 0.05 level were those difference between front and read paws, and the interactions between this effect and the strain, and between this effect and the left/right side effect; and interactions with strain effects. Sex effects showed no trends towards significance.
