Table 2. Overview of ICCs and parameters implemented in the analysis of Bland-Altman plots.

Depicted are the grand mean (mean of both measurement sessions), bias, random error component and upper/lower limits of agreement (ULOA/LLOA, respectively) for inter- and intra-day comparisons of all intervals in the AP and ML direction.
