Box and whisker plots of the kinematic and clinical assessments. Circles mark outliers that rest between 1.5- and 3-times the inter quartile range, stars indicate outliers that lie beyond 3-times the inter quartile range. We analyzed skill transfer by comparing the differences of the weeks 1 and 2; for the retention part, we evaluated differences between day 4 and day 3 of week 2. The retention p-values are Bonferroni-corrected for multiple testing, because the long-term retention test was done with a subgroup of this data set
