Figure 9. A scatter plot matrix of the principal component (PC) scores in the Cleft and Control groups with a histogram in the diagonal cells. PCs 1-9 explain 90.5% of the shape variation across samples. Pink denotes facial configurations in the male Control group (male); green denotes those in the male Cleft group; red denotes those in the female Control group; and cyan denotes those in the female Cleft group. The PCs are defined as +1 SD (yellow) and -1 SD (blue) in the top column. For example, the top column indicates that a +1 SD value of PC2 represents a smaller facial height, which was represented as yellow (1 SD). The histogram shows that the bimodal distribution and female patients in the Cleft group (cyan) showed a greater PC2 value, suggesting that the female Cleft group had a smaller facial height
