Table 3. Statistical analysis of the evaluation of secondary measures.
Intra-class correlation coefficient (ICC) regarding the inter-rater reliability (ICC 2,6) and the intrarater reliability (ICC 3,6) according to the Shrout and Fleiss convention. Additionally the Variance of Components Analysis which allows for covariate effects is displayed including the 95% confidence interval for all primary measurements.
