Box plot representation of Kruskal–Wallis analysis of the overall scores of the 9 reconstructed faces. The interior bars indicate the medians while the error bars display the inner limits (1.5 X interquartile range). The rectangular boxes denote the homogeneity subset. Identical letters imply non-significant differences, while different letters infers significant differences (Kruskal–Wallis test, P < 0.05)
