Mean diff is the mean of the difference between the measured values and the average value; SD diff is the standard deviation of the different value; 95% LOA = Mean diff ± 1.96 × SD diff; 95% LOA LB (95% CI of the LOA) = 95% Limits of agreement Lower Boundary (95% Confidence intervals of the limits of agreement); 95% LOA UB (95% CI of the LOA) = 95% Limits of agreement Upper Boundary (95% Confidence intervals of the limits of agreement); CR (Repeatability Coefficient) = SD diff × 1.96√2 = the smallest real different.
