Fig. 4From: Application of intraoral scanner to identify monozygotic twinsThe difference in the mean (horizontal line), standard deviation (box), and the 95% confidence intervals (whiskers) (a) and the dispersion of individual values (b) between the intra-subject (ISD) and intra-twin group (ITD). The lower dashed line indicates the upper 99% tolerance interval with 99% confidence (73 μm) of the intra-subject deviation values. The upper dashed line indicates the lower 99% tolerance interval with 99% confidence (138 μm) of the intra-twin deviation valuesBack to article page
