Table 2 The mean (standard deviation) of each mandibular morphometric parameter for randomized head positions, as well as the intra-rater and inter-rater reliability in terms of intra-class correlation coefficients (ICC) and coefficient of variation (CV) for the senior and junior examiner

The p values with an asterisk (*) calculated from the paired t test indicate that the differences in the measurement between examiners is less than 0.05
ICC ₁ Intra-rater correlation coefficient, ICC ₂ Inter-rater correlation coefficient
p value: p values of the paired-sample t test of the measurements between senior and junior
* Significant difference in the measurement between examiners
