Bland-Altman plot with marginal histograms for interobserver and intraobserver agreement in assessing the reliability of LACI measurement. Panel A: Intraobserver variability of LACI. Panel B: Interobserver variability of LACI. Bias, mean of differences between the two experts, Upper LoA, upper level of limits of agreement = mean of differences + 1.96 standard deviations; Lower LoA, lower level of limits of agreement = mean of differences − 1.96 standard deviations; r, Pearson correlation coefficients; ICC, Intraclass correlation coefficient; SEM, standard error of measurement.
