Figure 2

Mean difference among OSA and control groups for the following skeletal angles: (A) SNA, (B) SNB, (C) ANB, (D) NSBa, (E) U1-L1, (F) U1-SN. ANB = A point-nasion-B point angle, CI = confidence interval, IV = inverse variance, NSBa = nasion-sella-basion angle (cranial base flexure angle), SD = standard deviation, SNA = sella-nasion to A point angle, SNB = sella-nasion to B point angle, U1-L1 = upper incisor to lower incisor angle, U1-SN = upper incisor to nasion-sella angle.
