* Linear regression analysis
Y_x: Total mesiodistal width of maxillary canine and first and second premolars (average of both sides)
Y_m: Total mesiodistal width of the mandibular canine and first and second premolars (average of both sides)
X₂: total mesiodistal width of the maxillary first molar and mandibular central incisor
