Differences were tested by logistic regression analysis adjusted for age, gender and body mass index (BMI).
OR = odds ratio; CL = confidence level; AUC = area under the curve; ss-n-pg = sagittal jaw relation; s-n-ss = maxillary prognathia; s-n-pg = mandibular prognathia; NL/ML = vertical jaw relation; NSL/NL = maxillary inclination; NSL/ML = mandibular inclination.
