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
