  1. Regression results of raw length regressions between corresponding digit elements. Note that elements of digits II and III are close to identical in length in all species as shown by intercepts near 0 and slopes close to 1 with very little error. This is also reflected in tight correlations between digits II and III, which are nearly all significantly stronger than any other between-digit correlations (the relatively weaker results in metatarsals comparisons are caused by a single high-leverage outlier, Diprotodon optatum). r, Pearson correlation coefficient; dz, difference of z-score transformed correlations; p, significance.
