Table 2 Inter-group comparison of dentofacial deformity and dimension of airways. *Negative values indicate degree of inter-side asymmetry in millimeters. **Post-tests were conducted only for variables with a significant inter-group difference in the primary test
|  | Group 1 (JIA+): JIA with dentofacial deformity Median (25–75 quartile) | Group 2 (JIA-): JIA without dentofacial deformity Median (25–75 quartile) | Group 3 (Ctr): Controls Median (25–75 quartile) | Primary statistical test | Post-tests** |
