a Four typical cases of pre-ceph, post-ceph, and spost-ceph. Based on these pre-cephs, their landmarks, profile lines, and predicted amounts of surgical movement, GPOSC-Net generated corresponding spost-cephs. b Landmark distance errors (LDE, unit: mm) of post-ceph and spost-ceph measured by two orthodontists (ODs) for internal and external test sets. c LDEs of X-coordinates (unit: mm) of post-ceph and spost-ceph. d LDEs of Y-coordinates (unit: mm) of post-ceph and spost-ceph. Box plots illustrate the median, interquartile range (box), and whiskers extending to 1.5 times the range, with outliers represented as individual points. e Successful prediction rates (SPR) for each landmark in terms of percentages as determined by two ODs for internal and external test sets.
