  1. Mean difference (mm); differences in mean when comparing two methods stated in millimeters. Limits of agreement; Limits stating the position of 95% of measurement. Results shown are a subsection out of 48 possible combinations. For interrater analysis the second measurements made by each rater was compared to each other
