Summary of the agreement statistics, quantified as the Concordance Correlation Coefficient (CCC), bias correction error and Bland-Altman Limits of Agreement (LOA) interval. The best unbiased estimates are given with the 95% confidence intervals given in parentheses. The units of LOA intervals are the same as the body composition index. CCC and bias correction are dimensionless.
