From: Accuracy of facial skeletal surfaces segmented from CT and CBCT radiographs
Box plots showing the trueness of the segmented facial surface models indicated by the distances of the radiographically derived models from the direct optical scans, following their best-fit approximation. The Mean Absolute Distances (MAD) and the standard deviations of the absolute distances (SD) between the superimposed surface models are shown. The lines connect variables that show significant differences (p < 0.05) detected through Kruskal–Wallis, followed by Mann–Whitney U test (Bonferroni adjusted). Outliers are shown as black circles (further from the median more than 1.5 times the IQR).
