Table 4 Analysis of MRI findings after excluding deformity vs. MOC, corresponding SDS-values and centiles

From: Is early TMJ involvement in children with juvenile idiopathic arthritis clinically detectable? Clinical examination of the TMJ in comparison with contrast enhanced MRI in patients with juvenile idiopathic arthritis

MRI enhancement without deformity
Factor Examination method T-test p-value Mean difference (CI95 lower, CI95 upper)
Maximal mouth opening capacity Orthodontic (n = 51) 0.506 1.2 (−2.4, 4.7)
Rheumatologic (n = 50) 0.719 −0.7 (−4.4, 3.0)
SDS values Orthodontic (n = 47) 0.698 −0.1 (−0.8, 0.5)
Rheumatologic (n = 46) 0.265 −0.4 (−1.2, 0.3)
Centiles Orthodontic (n = 47) 0.683 −3.6 (−21.0, 13.9)
Rheumatologic (n = 46) 0.270 −10.5 (−29.5, 8.5)
  1. T-test to compare the MRI findings to the MOC’s and the corresponding SDS-values and centiles after excluding patients with deformity. Mean difference between groups with upper and lower 95 % confidence interval (CI95) is provided. All continuous variables were normally distributed
  2. *p-value < 0.05
