Table 1. Statistical analysis of the evaluation of primary measure “lumen areas”.
Intra-class correlation coefficient (ICC) regarding the inter-rater reliability (ICC 2,6) and the intra-rater 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.
