TABLE 6.

Summary of directional differences among groups of study. all dots (red and black dots) indicate the existence of directional dissimilarities, which means the p-value of the comparison is statistically significant at the p<0.05 level. The “axes” column demonstrates which two axes are compared to each other. Red dots indicate that first axis in the “axes” column has a higher value of the computed feature in “Features” column than does the second axis, while black dots indicate the second axis has a higher value than the first axis.
