Fig. 5From: A novel method for 3D face symmetry reference plane based on weighted Procrustes analysis algorithmBoxplot of position error for upper face, middle face, lower face group. The black asterisks signify P < 0.05 between WPA algorithm and PA algorithm group. The yellow and green asterisks indicate statistical significance for position error of different regional groups using a one-way ANOVA followed by Tukey’s multiple comparison test where P < 0.05, the circles within the boxplot represent outliersBack to article page
