Figures & data
Figure 1 Measurements of craniofacial skeletal parameters on cone-beam computed tomography (CBCT). Maxillary length: distance between anterior and posterior nasal spine; anterior maxillary width: distance between left and right upper 3 dentin-enamel junction; posterior maxillary width: distance between the left and right maxillary tuberosity; mandibular width: distance between left and right 3D Gonion; mandibular total length: distance between the 3D condyle and mental protuberance; mandibular body length: distance between the angle of the mandible and mental protuberance; mandibular ramus height: distance between the 3D Gonion and condyle.

Figure 7 Two phenotypes of catathrenia identified in the study, compared with OSA. Data of OSA was extracted from reference.Citation49 Patients with catathrenia in cluster 2 exhibit similarities to those with OSA on several parameters, while those in cluster 1 do not.
