Independent variables entered in each model: sex, SNA angle, ANB angle,  SN/MP angle, and NSBa angle, with variables having a p value above 0.1 removed from the model. Results of the multiple linear regressions are presented as β (SE); , coefficient of determination. Sig., level of significance; S, statistically significant; NS, not statistically significant.
