Dv, deviated side; NDv, nondeviated side; SD, standard deviation; ΔNDv−Dv, difference between the NDv and Dv; Me, menton; MFmid, midpoint of bilateral mental foramen; Go, gonion; MSP, midsagittal plane; MHP, mandibular horizontal plane; FHP, Frankfort horizontal plane; MnMSP, mandibular midsagittal plane; -, not applicable.
Values in the same row with no superscript are not statistically significant, and those with different superscript letters (a,b,c) are significantly different at P < 0.05 according to a one-way analysis of variance with Tukey’s post-hoc test.
Paired t test was performed to compare the Dv and NDv; significant difference at *P < 0.05, **P < 0.01, and ***P < 0.001 between the Dv and NDv.
